fix(ci): robustify --skip-patch-agents help assertions against width truncation

The three smoke tests (install/repair/init) were red on GitHub Actions because
Rich/Typer truncates long flag tokens with U+2026 at width-dependent boundaries.
Locally COLUMNS=200 (set in _run) is honored; on CI under pytest stdout capture
the effective width clips to ~80, rendering --skip-patch-agents as
'--skip-patch-age…'. CI has been red on every push since 2b093dc (#08.1-04).

Replace the literal-flag substring assertion with two width-stable anchors:
- 'skip-patch-ag' — short prefix that survives any reasonable truncation
- 'D-LOCK-06' — unique description tag that always renders intact via word-wrap

This still verifies the flag is documented with the right rationale, without
coupling the test to terminal width.
