🎯 Implement shared location selection for batch installations

- Ask installation locations ONCE at the beginning for all settings and hooks
- Eliminate repeated prompts during batch installation
- Add sharedInstallLocations parameter to individual functions
- Use shared locations when provided, fall back to individual prompts otherwise
- Show clear message about selected locations before installation begins

Flow:
1. User runs: --setting=model/use-sonnet,telemetry/enable-telemetry
2. CLI asks ONCE: 'Where would you like to install settings and hooks?'
3. User selects locations (e.g., user, project, local)
4. CLI shows: 'Will install settings and hooks in: user, project, local'
5. All settings install to those same locations automatically
6. No additional prompts, CLI exits after completion

Prevents the frustrating loop where each component shows its own
installation menu, creating a better user experience for batch operations.
