* fix: scale progress bars based on terminal width
Resolves#231
Progress bars (coloredBar/quotaBar) were hardcoded to width 10,
causing line wrapping in narrow terminals.
Now bars scale dynamically based on process.stdout.columns:
- Wide terminal (>=100 cols): width 10 (default)
- Medium terminal (60-99 cols): width 6
- Narrow terminal (<60 cols): width 4
Affected files:
- src/render/session-line.ts (context bar + usage bars)
- src/render/lines/identity.ts (context bar in expanded layout)
- src/render/lines/usage.ts (quota bars in expanded layout)
* fix: also check COLUMNS env var as fallback for bar width
For cross-platform compatibility (zsh, macOS, Windows),
getBarWidth() now also checks process.env.COLUMNS when
process.stdout.columns is unavailable (non-TTY, piped output).
* refactor: extract getAdaptiveBarWidth to shared utility
- Remove duplicated getBarWidth() from 3 render files
- Add src/utils/terminal.ts with exported getAdaptiveBarWidth()
- Add Math.floor() for consistency with getTerminalWidth()
- All 3 render files now import from shared utility (DRY)
* test: add unit tests for getAdaptiveBarWidth
Tests cover:
- Narrow terminal (<60 cols) → 4
- Medium terminal (60-99 cols) → 6
- Wide terminal (>=100 cols) → 10
- Boundary values (59, 60, 99, 100)
- Non-TTY/piped output (undefined columns) → 10 (default)
- Fallback to COLUMNS env var
- No terminal info at all → 10 (default)
* style: simplify JSDoc to match project comment style
