feat(start-work): add plan name normalization and quote stripping

- Add WRAPPING_QUOTES_PATTERN to parse-user-request.ts to strip quotes from plan names
- Add normalizePlanLookupValue() to context-info-builder.ts for slug normalization
- Enhanced findPlanByName() with normalized exact and partial matching
- Allows human-readable plan names (e.g., "my feature plan") to match slugged filenames (e.g., my-feature-plan.md)
