Problem

When the terminal window is narrow, the status line content overflows and wraps, making it hard to read:

Context ░░░░░░░░░░ 4% │ Usage ███░░░░░░░ 27% (2h 49m / 5h) | ██░░░░░░░░ 16% (5d 5h / 7d)

The progress bars (coloredBar / quotaBar) are hardcoded to width: 10 in session-line.ts, lines/identity.ts, and lines/usage.ts. The render function already detects terminal width via getTerminalWidth() and wraps lines, but the bars themselves never shrink.

Proposed Solution

Dynamically scale the bar width based on process.stdout.columns. For example:

• Wide terminal (≥100 cols): keep width: 10 (current default)
• Medium terminal (60–99 cols): reduce to width: 6
• Narrow terminal (<60 cols): reduce to width: 4 or hide bars entirely, showing only the percentage

This way the most important information (percentages, reset times) stays visible even in small windows.

Current Behavior

• Bar width is always 10 characters regardless of terminal size
• Narrow terminals cause line wrapping via wrapLineToWidth, breaking the layout

Expected Behavior

• Bars scale down proportionally when terminal is narrow
• Critical info (percentages, times) is always visible
