Add Kung Fu meta-skill for discovering and installing skills (#42)

* ✨ Add Kung Fu meta-skill for discovering and installing skills

Like Neo downloading martial arts in The Matrix - this skill teaches Claude
how to discover, evaluate, and install AI agent skills from the ecosystem.

Sources include awesome lists (VoltAgent, composioHQ, sickn33) and skill
registries (openskills, skillkit). Goal-focused design trusts the executing
LLM to figure out implementation details.

* ♻️ Refine kungfu skill for token efficiency and consistency

Address Claude Code Review feedback:
- Tighten skill-format section (remove redundant code block)
- Convert workflows to nested XML for structural consistency
- Bump version to 1.2.0

+<objective>
+Discover, evaluate, and install AI agent skills from the ecosystem. Like Neo downloading kung fu in The Matrix - expand capabilities by finding and integrating new skills.
+</objective>
+
+<discovery-strategy>
+Search GitHub for skill collections using:
+- Repos matching "awesome*skills" or "claude*skills"
+- Repos containing SKILL.md files (query: `path:SKILL.md claude`)
+- Topics: claude-code, ai-skills, agent-skills
+
+Known curated collections (verify availability before citing):
+- VoltAgent/awesome-agent-skills
+- composioHQ/awesome-claude-code-skills
+- sickn33/antigravity-awesome-skills
+
+If curated lists are unavailable, search GitHub directly. Prioritize repos updated within 6 months with meaningful star counts.
+</discovery-strategy>
+
+<skill-format>
+Valid skills: SKILL.md with frontmatter (name, "Use when..." description, triggers). Optional scripts/tool for executables (require user approval before install).
+</skill-format>
+
+<quality-signals>
+**Evaluate:** GitHub stars, recent activity, SKILL.md quality, documentation, relevance to user's need.
+
+**Skip:** No SKILL.md, abandoned (no commits in 1+ year AND unresponsive), <10 stars (unless from trusted source), duplicates already-installed skill.
+</quality-signals>
+
+<security>
+If a skill includes executable scripts in `scripts/`, ALWAYS:
+1. Show the user the script contents
+2. Explain what the script does
+3. Get explicit approval before installing
+
+Never auto-execute downloaded scripts.
+</security>
+
+<installation>
+Install to the project's `.claude/skills/<skill-name>/` directory. For global installation, use `~/.claude/skills/`.
+
+**Before installing:**
+- Check for existing skill with same name
+- If conflict: ask user to overwrite, rename, or skip
+
+**After downloading:**
+- Validate SKILL.md parses without YAML errors
+- Confirm required frontmatter (name, description, triggers) exists
+- Test with `/skill <name>` or a natural trigger phrase
+
+**If install fails:** Remove any partially downloaded files and report the specific failure.
+</installation>
+
+<workflows>
+<search>Query GitHub and curated lists, evaluate candidates against quality signals, present top 3-5 options with name, description, star count, last update, and install instructions.</search>
+
+<install>Fetch skill, run security review if scripts present, validate format, install to skills directory, verify it loads.</install>
+
+<audit>List installed skills from `.claude/skills/`, check source repos for updates, identify unused skills for removal.</audit>
