fix: wrap long CLI paths in table output

[jottakka]

Summary

CLI tables now wrap long path cells instead of truncating them with Rich's ellipsis overflow. This keeps long Windows paths distinguishable in narrow terminals and avoids emitting the Unicode ellipsis that can render as corrupted text in some PowerShell/Codex sessions.

The fix covers libr search, libr list, libr docs, libr docs list, and libr docs search. The existing --format paths mode remains the full copyable-path output for search results.

Testing

• uv run --extra dev pytest tests/test_cli.py
• uv run --extra dev pytest
• Manual Rich rendering check with an 80-column console and a long Windows-style path across all CLI Path tables
