fix(tui): use consistent accent color for entire selected line in file selector

Previously, the selected line in @ fuzzy search and Tab completion used
accent color for prefix/label but muted color for description. Now the
entire selected line uses the accent color for better visual consistency.

fix: file @ autocomplete performance using fd

- Remove minimatch dependency from tui package
- Graceful degradation if fd unavailable (empty results)

Fix edit diff line number alignment and whitespace preservation

- Fix line numbers showing incorrect values for edits far from file start
  (e.g., 1,2,3 instead of 336,337,338). Skip count was added after displaying
  lines instead of before.

- Rewrite splitIntoTokensWithAnsi in pi-tui to preserve whitespace as separate
  tokens instead of discarding it. Wrapped lines now maintain proper alignment
  and code indentation.

- Update mom README: rename title, remove em-dashes for cleaner prose

feat: fuzzy file search with @ prefix

- Respects .gitignore and skips hidden files
- Pure Node.js implementation using readdir with withFileTypes
- No external dependencies (fd/find) required
- Also optimized Tab completion to use withFileTypes instead of statSync

Based on PR #60 by @fightbulc, reimplemented for performance.

fix: emoji text wrapping crash in pi-tui

Fixed crash when rendering text containing emojis followed by long content.
The breakLongWord function was iterating over UTF-16 code units instead of
grapheme clusters, causing emojis (surrogate pairs) to be miscounted during
line wrapping. Now uses Intl.Segmenter to properly handle multi-codepoint
characters.

  terminal to hang when text contained many / characters (e.g., URLs).
  Replaced complex regex with simple lastIndexOf approach. (#18)

  by adding missing return statement after handling arrow keys in
  autocomplete mode.

feat: add visual thinking level indicator via border colors

The horizontal borders around the input editor now change color based on
the current thinking level, providing immediate visual feedback:

- off: gray (default)

- Add public borderColor property to Editor component (packages/tui)
- Use borderColor instead of hardcoded chalk.gray for borders
- Add getThinkingBorderColor() helper in TuiRenderer
- Add updateEditorBorderColor() to apply color changes
- Update border color when:
  - Cycling with Tab key
  - Selecting via /thinking command
  - Restoring session with thinking level set

Fix viewport width issues in thinking selector and text rendering

Thinking selector fix:
- Replace hardcoded 50-character borders with DynamicBorder component
  that adjusts to viewport width
- Prevents crash when terminal is resized narrow

Text/Markdown rendering fixes:
- Fix Markdown wrapSingleLine to check if adding next character would
  exceed width BEFORE adding it (was checking AFTER, causing lines to
  be 1 character too long)
- Add word truncation in Text component for words longer than
  contentWidth (prevents long unbreakable words from exceeding width)

These fixes prevent "Rendered line exceeds terminal width" errors.
