jpmschweitzerandClaude f3e164b834 test sweep: cover core/input/ keytab + handlers (T-91) 
Adds test/terminal/input/input_test.dart — 58 unit tests covering
the keytab tokenizer, parser, unescape helper, KeytabRecord
toString shapes, Keytab.find modifier-matching rules, and the four
TerminalInputHandler implementations (CascadeInputHandler,
KeytabInputHandler, CtrlInputHandler, AltInputHandler).

Highlights:

- keytabUnescape: every documented backslash escape + \xHH hex.
- LineReader: peek/take/done, whitespace skip, readString
  (alphanumeric/underscore), readUntil (both exclusive and
  inclusive variants).
- tokenize: keyboard-name and key-define lines, comment + blank
  stripping, shortcut vs string actions, error paths on malformed
  input.
- KeytabParser: full mode-flag matrix, error paths on every
  defensive throw reachable through the public addTokens API
  (stray non-keyboard token, missing colon, modeStatus value other
  than '+'/'-', non-mode token after modeStatus, action token of
  wrong type, second token of wrong kind for both _parseName and
  _parseKeyDefine).
- KeytabRecord.toString covers every supported flag (Alt, Control,
  Shift, AnyMod, Ansi, AppScreen, KeyPad, AppCuKeys, AppKeyPad,
  NewLine, Mac).
- Keytab.find: -Shift / +AnyMod / -AnyMod gating, mode-flag
  filters (newLine, appKeyPad, appScreen, macos, appCursorKeys,
  keyPad), -Ansi (VT52) skip, fallthrough to fallback record,
  null when no key matches.
- KeytabInputHandler: every modifier combination's `*` placeholder
  expansion (1..8 inclusive), default-keytab fallback, no-match
  null, no-* passthrough.
- CtrlInputHandler: A..Z → 0x01..0x1A; null without ctrl, with
  shift / alt, or on non-letter keys.
- AltInputHandler: A..Z → ESC + uppercase; null without alt, with
  shift / ctrl, on macOS, or on non-letter keys.
- defaultInputHandler integration: keytab routing, fallthrough to
  CtrlInputHandler.

Coverage delta:
- core/input/handler.dart: 4/54 → 54/54.
- keytab.dart: 0/29 → 29/29.
- keytab_record.dart: 0/44 → 44/44.
- keytab_token.dart: 0/82 → 80/82 (the two remaining lines are
  defensive throws inside `_parseKeyboardNameDefine` /
  `_parseKeyDefine` that are unreachable from tokenize() — the
  callers only enter those functions after the `_isKeyboardNameDefine`
  / `_isKeyDefine` guards in the same file, so the inner readString
  always matches).
- keytab_parse.dart: 0/65 → 63/65 (the two remaining lines mirror
  the same shape — _parseName and _parseKeyDefine both check the
  first token's type, but addTokens only delegates to them after
  matching that type, so the throws are dead defensive code).
- keytab_default.dart: 0/4 unchanged — that's the file's own
  `void main()` debug entrypoint that prints the parsed default
  keytab; not part of the runtime contract.
- keytab_escape.dart: 0/14 → 14/14.
- Total project: 49.31% → 52.53%; coverage_floor bumped 49 → 52.

The 4 dead defensive throws are flagged but not removed in this
commit — they're a code-style call (defensive paranoia vs. dead-
code cleanup) that belongs in a separate review, not folded into a
test sweep.

jpmschweitzerandClaude 9331055b44 test sweep: cover EscapeParser + EscapeEmitter (T-91) 
Adds test/terminal/escape/parser_test.dart — 70 unit tests covering
the parser's dispatch surface end-to-end:

- single-byte controls (BEL, BS, HT, LF/VT/FF, CR, SO, SI),
- ESC sequences (D, E, H, M, =, >, 7, 8, ( name, ) name, unknown),
- CSI cursor moves (A/B/C/D/E/F/G/H/d/f) with default + 0-as-1
  fallback semantics,
- erase / scroll / line-insert/delete / chars (J, K, L, M, P, S, T,
  X, @, b, g, r),
- device attributes (c / >c / =c) and DSR (5, 6),
- window manipulation (CSI 8 t resize, CSI 18 t sendSize, ignored
  no-op codes, malformed CSI 8 t),
- mode set/reset (h/l, ? prefix for DEC modes — covering ?1, ?3,
  ?5, ?6, ?7, ?9, ?12, ?25, ?47, ?66, ?1000, ?1002, ?1003, ?1004,
  ?1005, ?1006, ?1007, ?1015, ?1047, ?1048, ?1049, ?2004, +
  unknown fallback),
- SGR styling (resets, set/unset for every attr, 16-colour
  foreground + background, 256-colour, 24-bit RGB, 39 / 49
  resets, unknown → unsupportedStyle),
- OSC 0/1/2 (BEL- and ST-terminated), unknown OSC, incomplete
  sequence held back across writes,
- unknown CSI final byte → unknownCSI,
- token bookkeeping (tokenBegin / tokenEnd advance with consumed
  bytes).

Plus EscapeEmitter — every reply string format (primary /
secondary / tertiary device attributes, operating status, cursor
position, bracketed paste, size).

Coverage delta:
- parser.dart: 0 / 462 → 504 / 514 (98.1%; the remaining 10 lines
  sit inside the `// ignore: dead_code` SGR loop, which I'm
  surfacing for separate review rather than extending tests
  around).
- emitter.dart: 1 / 11 → 11 / 11.
- Total project: 43.20% → 49.38%; coverage_floor bumped 43 → 49.

Two real source-code issues found while writing tests, fixed in
the same commit:

1. Swapped docstrings on `_escHandleSetAppKeypadMode` /
   `_escHandleResetAppKeypadMode`. The function names + dispatch
   table + bodies all match the VT spec correctly (ESC = enables,
   ESC > disables); only the doc-comments were swapped. Now read
   the right way around.
2. `case 10061000:` in `_setDecMode` was unreachable (no DEC mode
   has that value). Almost certainly a typo where `case 1006:`
   meant to glue onto `case 1000:` but a newline went missing.
   Mode 1006 is already handled separately at its own clause as
   `MouseReportMode.sgr`. Removed.

jpmschweitzerandClaude c233b7607d test sweep: cover Buffer (T-91) 
Adds test/terminal/buffer/buffer_test.dart — 67 unit tests against
the Buffer orchestrator on top of BufferLine. Drives a fake
TerminalState through writes, cursor moves, scroll regions,
erase commands, line insert/delete, resize (with and without
reflow), word-boundary lookup, getText, and the toString debug
dump.

Coverage delta:
- buffer.dart: 0 / 260 → 260 / 261 (one while-loop-body line
  Dart coverage doesn't instrument distinctly; the loop's effect
  is exercised end-to-end by the reflow-pad test).
- Total project: 39.12% → 43.20%.
- pubspec.yaml `coverage_floor:` bumped 39 → 43.

Notes:
- The fake TerminalState (`_State`) is a per-file impl rather than
  a shared fixture; it stays close to the test that exercises it
  and avoids forcing other terminal tests to depend on a one-shape-
  fits-all stub.
- Tests that walk through `lineFeed` use `lineFeedMode: true` so
  the column resets between newlines — otherwise the saturated
  cursor X from a previous full-width write spills the next write
  onto an extra line via `writeChar`'s autoWrap branch.

This closes the `core/buffer/` sub-area for T-91 — every leaf file
in `lib/src/terminal/src/core/buffer/` is now at >= 96% line
coverage; the only outliers are Dart-coverage-instrumentation
quirks, not real gaps.

jpmschweitzerandClaude c744c8ce4b test sweep: cover BufferLine + CellAnchor (T-91) 
Adds test/terminal/buffer/line_test.dart — 51 unit tests covering
BufferLine and CellAnchor, hitting every reachable line in
lib/src/terminal/src/core/buffer/line.dart (192 / 192).

Coverage delta:
- line.dart: 0 / 194 → 192 / 192 (file shrank by two lines after
  the prior commit's iteration fix folded two for-loop heads into
  for-each-toList).
- Total project: 36.39% → 39.12%.
- pubspec.yaml `coverage_floor:` bumped 36 → 39 in lockstep.

Highlights:
- All packed-cell encodings (foreground/background/attrs/content
  channels, codepoint+width packing, CellData round-trips).
- `eraseRange` wide-char neighbor extension on both ends.
- `removeCells` / `insertCells` shift logic, anchor reposition, and
  the wide-tail-erase branch (insertCells case where the post-shift
  last cell carries a wide marker).
- `resize` exercising the [64, 256) capacity-doubling branch and
  the >=256 +32 branch separately.
- `getTrimmedLength` cols-clamp behaviour for null/over-capacity.
- `getText` skip-trailing-wide-char branch.
- `CellAnchor` lifecycle: detached construction, `reposition`,
  `reparent` (both detached→attached and between owners), `dispose`,
  attached y/offset via a real IndexAwareCircularBuffer.

Also cleans up five `unrelated_type_equality_checks` analyze infos
in test/terminal/buffer/range_test.dart by typing the RHS as Object
when intentionally probing the type-mismatch branch of operator==.

jpmschweitzerandClaude eb32396bd4 test sweep: cover BufferRange family (T-91) 
Adds test/terminal/buffer/range_test.dart — 38 unit tests covering
the small pure-Dart files in lib/src/terminal/src/core/buffer/:

- cell_offset.dart       23 / 23  (was 0 / 23)
- range.dart             13 / 13  (was 0 / 13)
- segment.dart           13 / 13  (was 0 / 13)
- range_line.dart        30 / 30  (was 0 / 30)
- range_block.dart       48 / 48  (was 0 / 48)

Total project line coverage 34.90% → 36.39%; coverage_floor in
pubspec.yaml bumped 34 → 36 in lockstep.

Tests exercise the abstract BufferRange operator==/hashCode/toString
via a local _StubRange (BufferRangeLine and BufferRangeBlock both
override those, so the base versions are otherwise unreachable —
worth a stub rather than carving the lines out of coverage). The
denormalized-input branches in Block contain/toSegments/extend get
explicit cases too.

Pure Dart, no Flutter dependency — uses package:test/test.dart and
runs in <100ms.

First batch under T-91; line.dart and buffer.dart land in subsequent
commits with their own floor bumps.

jpmschweitzerandClaude a67a768592 restore semantic bold rendering in terminal panes (T-73) 
Bold attributes from terminal escapes now render in a real bold
weight instead of being silently flattened.

- pubspec.yaml: register JetBrainsMono Bold + BoldItalic at
  weight 700 under family JetBrainsMono. Files already shipped on
  disk; only the registration was missing.
- assets/licenses.yaml: bump JetBrainsMono weights_bundled to
  [Regular, Italic, Bold, BoldItalic] per D-42 (the entry must
  match what is actually wired into the family).
- lib/src/terminal/src/ui/painter.dart: revert the `bold: false`
  override and drop the workaround comment. Bold now flows from
  CellFlags.bold to TextStyle.fontWeight.
- test/terminal/painter_bold_metrics_test.dart: load Regular and
  Bold via FontLoader and assert paragraph maxIntrinsicWidth is
  identical (cell-grid drift = 0). JetBrainsMono Bold's monospace
  by spec; this test is the canary for the day someone swaps the
  font.
- test/goldens/goldens/{ci,linux}/clide_button.png: regenerate.
  ClideButton's label renders slightly heavier on the bold variant
  (expected — 0.28% pixel diff before regen).

Earlier perception of over-bolding in the Claude pane was
synthetic-bold smearing (Flutter overpaints when no Bold.ttf is
registered for the family), not legitimate bold rendering. Visual
A/B confirms a real Bold face renders crisp emphasis without the
smear, so no per-pane renderer config is needed.
