docs: Update all documentation to use new 'analyze' command

- Update Chinese README (README.zh-CN.md) with new preset flags
- Update docs/features/*.md (PATTERN_DETECTION, HOW_TO_GUIDES, BOOTSTRAP_SKILL_TECHNICAL)
- Update scripts/bootstrap_skill.sh to use 'skill-seekers analyze'
- Update scripts/skill_header.md command examples
- Update tests/test_bootstrap_skill.py assertions
- Fix CHANGELOG.md historical entry with correct command name

All references to 'skill-seekers-codebase' updated to 'skill-seekers analyze'
except where needed for backward compatibility (pyproject.toml, E2E tests).

Related to Phase 1 implementation from previous commits.
