Security auditor, personas, orchestration, docs catalog & roadmap (#35)

Closes the remaining gaps vs alirezarezvani/claude-skills across trust, content
types, discoverability, and community.

Security (trust signal + useful):
- scripts/skill-audit.mjs scans skills/*/SKILL.md + each skill's scripts/ for
  prompt injection, exfiltration, dynamic code exec, destructive shell, secrets,
  and hidden text. HIGH fails CI (.github/workflows/skill-audit.yml) + a badge.
- New skill-security-auditor skill teaches the same review (production tier).

Content types:
- output-styles/ — 4 personas (Startup CTO, Growth Marketer, Solo Founder,
  Product Leader) as Claude Code output styles; --agent claude installs them too.
- ORCHESTRATION.md — Skill Chain / Multi-Agent Handoff / Domain Deep-Dive /
  Solo Sprint patterns.

Discoverability:
- scripts/build-docs.mjs generates a server-rendered, SEO-indexable
  web/catalog.html of all skills (built in the Pages deploy; gitignored).
  Linked from README + playground.

Community:
- ROADMAP.md (now/next/later + good-first-issues).

README badges/sections, TIERS (47 production), CHANGELOG, package.json files,
and exports/web index all updated. SkillCheck + security audit + exports verified.

+# Output Styles (Personas)
+
+Claude Code **output styles** that change the assistant's overall voice and default skill
+loadout. Switch with `/output-style` in Claude Code, or install them with the skills.
+
+| Persona | Voice | Leans on |
+|---|---|---|
+| `Startup CTO` | Decisive, cost-aware, ships | architecture, specs, tech debt |
+| `Growth Marketer` | Funnel & experiment driven | positioning, GTM, content, A/B tests |
+| `Solo Founder` | Ruthless prioritisation, leverage | prioritisation, positioning, ops |
+| `Product Leader` | Outcome-oriented, crisp comms | PRDs, OKRs, roadmap, stakeholder comms |
+
+## Install
+
+```bash
+./scripts/install.sh --agent claude     # installs skills + agents + commands + output-styles
+# or copy manually:
+cp output-styles/*.md ~/.claude/output-styles/
+```
+
+Then run `/output-style` in Claude Code and pick one.
