feat(tui): wrap model usage columns

[jimyag]

Summary

The aggregate TUI Models column could be clipped when the rendered model list was wider than the terminal. This change keeps the complete model usage details visible by wrapping them within the available column width.

Changes

• Calculate the final Apps and Models column widths before constructing rows.
• Keep model entries together when possible and hard-wrap an individual entry only when it exceeds the available width.
• Size data rows, the totals row, and the Models header for their wrapped content so normal table navigation can scroll through it.
• Add helper and narrow-terminal rendering tests.

Verification

• cargo build --quiet
• cargo test --quiet (453 passed)
• cargo clippy --quiet -- -D warnings
• cargo doc --quiet
• cargo fmt --all -- --check
• git diff --check

Notes

• No configuration, data format, or analyzer behavior changes.
• Review focus: final column-width allocation and Ratatui multiline row scrolling behavior.

Summary by CodeRabbit

• Bug Fixes
  • Improved aggregate statistics table layout on narrow displays.
  • Long model-usage text, headers, and totals now wrap cleanly instead of being clipped.
  • Ensured all model entries remain visible when space is limited.
  • Improved column sizing for Unicode and wide-character names, including CJK text.

📝 Walkthrough

Walkthrough

The TUI aggregate statistics table now measures terminal display widths, wraps model usage text, and adjusts header, data, and totals row heights. Tests cover CJK text and narrow-terminal rendering.

Changes

Aggregate table wrapping

Layer / File(s)	Summary
Model usage text wrapping src/tui.rs, src/tui/tests.rs	wrap_model_usage_text uses display widths, keeps entries together when possible, hard-wraps oversized entries, and verifies CJK wrapping.
Aggregate table layout integration src/tui.rs, src/tui/tests.rs	The table precomputes Apps and Models widths, applies wrapped cells to the header, data, and totals rows, sizes rows from wrapped content, and tests narrow-terminal rendering.

Priority: ⬇️ Low — Defer the TUI column-wrapping change because it is a narrow rendering improvement with low issue severity and no configuration, data-format, or analyzer behavior impact.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: ⚪ Minimal · up to 8e697

The aggregate TUI table now wraps model usage to terminal cell width and preserves entries on narrow displays, including wide Unicode names. No current merge-blocking risk is identified.
