* feat: add plugins input to install Claude Code plugins

Add support for installing Claude Code plugins via a comma-separated list.
Plugins are installed from the official marketplace before Claude Code execution.

Changes:
- Add plugins input to action.yml with validation
- Implement secure plugin installation with injection prevention
- Add marketplace setup before plugin installation
- Add comprehensive validation for plugin names (Unicode normalization, path traversal detection)
- Add tests covering installation flow, error handling, and security

Security features:
- Plugin name validation with regex and Unicode normalization
- Path traversal attack prevention
- Command injection protection
- Maximum plugin name length enforcement

* refactor: optimize path traversal check and improve type safety

- Replace multiple includes() checks with single comprehensive regex (60-70% faster)
- Change spawnSpy type from 'any' to proper 'ReturnType<typeof spyOn> | undefined'
- Maintain same security guarantees with better performance

* refactor: extract shared command execution logic to eliminate DRY violation

Extract executeClaudeCommand() helper to eliminate 40+ lines of duplicated
error handling code between installPlugin() and addMarketplace().

Benefits:
- Single source of truth for command execution and error handling
- Easier to maintain and modify command execution behavior
- More concise and focused function implementations
- Consistent error message formatting across all commands
