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.

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==.

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.

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.
