feat: Merge PR #249 - Bootstrap skill with fixes and MCP optionality

Merged PR #249 from @MiaoDX with enhancements:

Bootstrap Feature:
- Self-bootstrap: Generate skill-seekers as Claude Code skill
- Robust frontmatter detection (dynamic line finding)
- SKILL.md validation (YAML + Markdown structure)
- Comprehensive error handling (uv check, permission checks)
- 6 E2E tests with venv isolation

MCP Optionality (User Feature):
- MCP removed from core dependencies
- Optional install: pip install skill-seekers[mcp]
- Lazy loading with helpful error messages
- Interactive setup wizard on first run
- Backward compatible

Bug Fixes:
- Fixed codebase_scraper.py AttributeError (line 1193)
- Fixed test_bootstrap_skill_e2e.py Path vs str issue
- Updated test version expectations to 2.7.0
- Added httpx to core (required for async scraping)
- Added anthropic to core (required for AI enhancement)

Testing:
- 6 new bootstrap E2E tests (all passing)
- 1207/1217 tests passing (99.2% pass rate)
- All bootstrap and enhancement tests pass
- Remaining failures are pre-existing test infrastructure issues

Documentation:
- Updated CHANGELOG.md with v2.7.0 notes
- Updated README.md with bootstrap and installation options
- Added setup wizard guide

- scripts/bootstrap_skill.sh - Dynamic frontmatter, validation, error handling
- src/skill_seekers/cli/install_skill.py - Lazy MCP loading
