**Summary:**
Applied the same selective replacement logic from Install-Claude.ps1 to Install-Claude.sh (Bash version).
**Changes:**
- Added `backup_and_replace_directory` function for folder-level operations
- Modified `install_global` to use selective replacement for .claude, .codex, .gemini, .qwen
- Modified `install_path` to use selective replacement for local folders and config directories
- Maintained `merge_directory_contents` for backward compatibility
**New Installation Flow:**
1. Backup entire existing directory to timestamped backup folder
2. Only remove items in destination that match source item names
3. Copy source items to destination
4. Preserve all other files in destination directory
**Benefits:**
- Protects user-created files and session data
- Only updates files that come from installation source
- Safer incremental updates
- Consistent behavior across PowerShell and Bash versions
**Example:**
Source: .claude/{commands, workflows, scripts}
Destination before: .claude/{commands, workflows, custom.json, .workflow/}
Destination after: .claude/{commands, workflows, scripts, custom.json, .workflow/}

- Redirect menu prompts to stderr to prevent capture by command substitution
- Fixes issue where installation options were not visible to user
- Menu now displays correctly: "Global" and "Path" installation modes
Issue: When get_user_choice output was captured by $(command),
the menu display was suppressed because stdout was being captured.
Solution: Output all user-facing prompts to stderr (&2) while
keeping the selected value on stdout for function return.
