Add droid and cursor sync targets, extract shared path helpers

- Add sync --target droid (skills to ~/.factory/skills/)
- Add sync --target cursor (skills + MCP to .cursor/)
- Extract expandHome/resolveTargetHome to src/utils/resolve-home.ts
- Remove duplicated path helpers from convert.ts and install.ts
- Bump version to 0.6.0
