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.

+1. **Context** — What is the issue motivating this decision?
+2. **Decision** — What is the change being proposed/made?
+3. **Consequences** — Positive, Negative, Neutral outcomes
+4. **Alternatives Considered** — Table of options with pros, cons, verdict
+5. **References** — Related ADRs, RFCs, external links

+| State | Meaning |
+|-------|---------|
+| Proposed | Under discussion, not yet approved |
+| Accepted | Approved and in effect |
+| Superseded | Replaced by a newer ADR (link to replacement) |
+| Deprecated | No longer relevant |
+
+## ADR Index Page
+
+Maintain an `ADR-Index` wiki page listing all ADRs grouped by status.
+
+## Integration with Sprint Workflow
+
+- ADRs created via `/adr create` during project initiation or planning
+- ADR status checked during `/project status`
+- Sprint planning can reference ADRs in issue descriptions
