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.
