feat(marketplace): hook migration, projman commands, optimizations [BREAKING]

Remove all SessionStart and PostToolUse hooks across the marketplace,
retaining only PreToolUse safety hooks and UserPromptSubmit quality hooks.
Add /project and /adr command families, /hygiene check, /cv status.
Create 7 new projman skills for project lifecycle management.
Remove /pm-debug, /suggest-version, /proposal-status commands.

+# Risk Register
+
+## Wiki Page
+
+Page name: `Risk-Register: {Name}` (e.g., `Risk-Register: Driving School SaaS`)
+
+### Dependency Header
+
+```
+> **Project:** {Name}
+> **Sprint:** N/A (project-level, reviewed per sprint)
+> **Issues:** N/A
+> **Parent:** Project: {Name}
+> **Created:** YYYY-MM-DD
+> **Status:** Active | Archived

+## Risk Register Template
+
+| ID | Risk | Probability | Impact | Score | Mitigation | Owner | Status |
+|----|------|------------|--------|-------|------------|-------|--------|
+| R1 | Example risk description | Medium | High | 6 | Mitigation strategy | Dev | Open |
+
+## Scoring
+
+| Probability | Value |
+|-------------|-------|
+| Low | 1 |
+| Medium | 2 |
+| High | 3 |
+
+| Impact | Value |
+|--------|-------|
+| Low | 1 |
+| Medium | 2 |
+| High | 3 |
+
+**Score** = Probability x Impact (1-9 range)
+
+## Risk Lifecycle
+
+| Status | Meaning |
+|--------|---------|
+| Open | Active risk, mitigation planned |
+| Monitoring | Risk identified but not yet actionable |
+| Mitigated | Mitigation applied, risk reduced |
+| Occurred | Risk materialized — track resolution |
+| Closed | No longer relevant |
+
+## Integration
+
+- `/project plan` creates initial risk register
+- `/project status` summarizes open risk count and top-3 by score
+- `/sprint-close` updates risk statuses in lessons learned
