* refactor(skills): add SKILL.md entrypoint to skill directories
Align skill source format with Open Skills standard: each skill
directory now contains a SKILL.md with name/description frontmatter
where name must match the directory name exactly. The installer
copies skill directories verbatim instead of generating SKILL.md.
- Add SKILL.md to both tracer bullet skill directories
- Strip name/description from workflow.md frontmatter (SKILL.md owns it)
- Installer reads metadata from SKILL.md, validates name matches dirname
- Install path in manifest CSV now points to SKILL.md
- Copy filter excludes OS/editor artifacts (.DS_Store, backups, dotfiles)
- Debug-guard validation messages, keep name-mismatch as hard error
- Add typeof guard for malformed YAML frontmatter
- Add negative test cases for parseSkillMd validation (Suite 30)
* fix(skills): improve quick-dev-new-preview description for LLM discovery
Add trigger context so LLMs know when to invoke the skill,
matching the "Use when..." pattern used by other skills.
* fix(cli): validate frontmatter name/description are strings in parseSkillMd
Prevents cleanForCSV() crash when YAML parses name or description as
a non-string type (number, object, boolean).
* fix(cli): address PR review findings (mkdtemp, regex escape, recursive filter)
- Replace Date.now() temp dir with fs.mkdtemp() in Suite 30 tests (F5)
- Replace unescaped RegExp with startsWith/slice for path prefix stripping (F7)
- Apply artifact filter recursively via fs.copy filter option (F8)
