Epic: Finder Integration for Project Lifecycle

[BugRoger]

Summary

Add Finder/file system integration to mirror PARA structure for non-markdown project assets. Extends the project lifecycle skills (#2) with file system synchronization.

Stub created: _sub/project-sync-finder/SKILL.md documents the planned interface.

Folder Structure

~/Projects/  (configurable base path)
├── 2026-03-31-quarterly-planning/
│   ├── Assets/
│   └── Documents/
└── _Archive/
    └── 2025-12-31-completed-project/

---

Configuration

Will read from .claude/config.md:

finder_projects_path: ~/Projects

---

Integration Points

On /create-project:

1. Create folder at ~/Projects/{due_date}-{slug}/
2. Create subfolders (Assets, Documents)
3. Optionally open folder in Finder

On /archive-project:

1. Move folder to ~/Projects/_Archive/
2. Handle missing folders gracefully

---

Implementation

The project-sync-finder sub-skill stub is already in place. Implementation needs:

1. Path expansion (~ to full path)
2. mkdir -p for folder creation
3. mv for archival
4. Idempotent operations (handle existing folders)
5. Error handling for permission issues

---

Acceptance Criteria

• Folder created at configured path on project create
• Subfolders (Assets, Documents) created
• Folder moved to _Archive/ on project archive
• Integration gracefully skipped if not configured
• Works on macOS (primary target)
