fix: address PR review feedback

- ClaudeSymlinkManager.uninstall() now returns count for accurate reporting
- install-command.ts uses return value instead of always incrementing
- claude-dir-installer.ts uses getCcsHome() directly instead of string manipulation
- Add TODO comments to tests explaining --install is a no-op
