feat: add iCloud vault support and launcher command installation

- Add new /install-claudesidian-command to create shell alias for launching vault from anywhere
- Add automatic iCloud Drive vault detection in init-bootstrap
- Add iCloud-specific search path with maxdepth 5 for nested structure
- Add fallback prompt asking about iCloud if vault not found
- Update README with launcher command documentation and usage examples
- Shell command auto-resumes existing sessions or starts new ones

This addresses user feedback about iCloud vault detection and adds convenient
shell launcher similar to obsidian-cli pattern.

+### iCloud Vault Search Implementation
+
+When searching for vaults, use this find command pattern:
+
+```bash
+# Standard locations (shallow search)
+find ~/Documents ~/Desktop -maxdepth 3 -type d -name ".obsidian" 2>/dev/null
+
+# iCloud location (deeper search needed due to nested structure)
+find ~/Library/Mobile\ Documents/iCloud~md~obsidian/Documents -maxdepth 5 -type d -name ".obsidian" 2>/dev/null
+
+# Home directory (shallow to avoid deep recursion)
+find ~ -maxdepth 2 -type d -name ".obsidian" 2>/dev/null
+```
+
+The iCloud path requires:
+- Higher maxdepth (5) due to nested folder structure
+- Escaped spaces in path name
+- Silent error handling (2>/dev/null) as many users won't have iCloud
+
