feat(observer): v11 — enhanced context extraction + 5-level sibling search + command enrichment (v0.5.42) #task-619

- extractContextFromNearby: span/div/p text fallback when pre/code not found (depth 0-8)
- collectSiblingButtons: extended to 5 parent levels, stop only when both action+reject found
- http-bridge: command enrichment — swap generic button text with actual command from description
- Fixes: cmd='Always run' now shows actual command text, Cancel button detection improved
