Path A (detached HEAD in externally managed worktree) was unreachable
because Step 1 halted on test failure before Step 1.5 could detect the
restricted environment. Reorder so detection runs first — Path A now
skips test verification entirely since the toolchain may not be available
in sandbox environments.

Re-detect externally managed worktree at cleanup time and skip removal.
Also fixes pre-existing inconsistency: cleanup now correctly says
Options 1 and 4 only, matching Quick Reference and Common Mistakes.

Update all skill references to use explicit requirement markers:
- REQUIRED BACKGROUND: For prerequisite understanding
- REQUIRED SUB-SKILL: For mandatory workflow dependencies
- Complementary skills: For optional but helpful related skills
Changes:
- Remove old path format (skills/collaboration/X → X)
- Add explicit "REQUIRED" markers to make dependencies clear
- Update Integration sections with categorized skill relationships
- Fix non-existent skill references
- Update cross-reference documentation in writing-skills
This makes it immediately clear which skills MUST be used vs optional references,
helping Claude understand and comply with skill dependencies.
- Update all 20 skill frontmatter names to match their directory names in lowercase
- Fix defense-in-depth name (was Defense-in-Depth-Validation)
- Fix receiving-code-review name (was Code-Review-Reception)
- Update all skill announcements and cross-references to use lowercase names
- Update commands redirects to reference lowercase skill names
Ensures consistent naming: skill directory names, frontmatter names, and documentation
references all use lowercase kebab-case format (e.g., brainstorming, test-driven-development)
