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.
