Move artifacts to ~/.claude-flow/ (outside repo)

- Store session artifacts in ~/.claude-flow/projects/{projectId}/sessions/{sessionId}/
- Artifacts no longer live in project directory - can't be accidentally committed
- Remove .claude-flow/ from .gitignore (not needed anymore)
- Update all IPC handlers and renderer to use projectId instead of projectPath
- Update prompts to remove worktree references
- Update README with new storage location
