feat: add interactive setup wizard with API validation and mismatch detection

Major improvements to plugin setup experience:

Setup Commands:
- Redesign /initial-setup as interactive wizard (MCP + system + project config)
- Add /project-init for quick project-only setup
- Add /project-sync for handling repository moves/renames
- Add Gitea API validation to auto-fill org/repo when verified

Configuration Changes:
- Move GITEA_ORG from system to project level (supports multi-org users)
- System config now only contains GITEA_URL and GITEA_TOKEN
- Project .env now contains GITEA_ORG and GITEA_REPO

Automation:
- Add SessionStart hook for projman and pr-review
- Automatically detects git remote vs .env mismatch
- Warns user to run /project-sync when mismatch found

Documentation:
- Unify configuration docs (remove duplicate in plugins/projman)
- Add flow diagrams to CONFIGURATION.md
- Add setup script review guidance to UPDATING.md
- Update COMMANDS-CHEATSHEET.md with new commands and hooks

Files added:
- plugins/projman/commands/project-init.md
- plugins/projman/commands/project-sync.md
- plugins/projman/hooks/hooks.json
- plugins/pr-review/commands/initial-setup.md
- plugins/pr-review/commands/project-init.md
- plugins/pr-review/commands/project-sync.md
- plugins/pr-review/hooks/hooks.json
- plugins/cmdb-assistant/commands/initial-setup.md
