YeonGyu-Kim ddf878e53c feat(write-existing-file-guard): add hook to prevent write tool from overwriting existing files
Adds a PreToolUse hook that intercepts write operations and throws an error
if the target file already exists, guiding users to use the edit tool instead.

- Throws error: 'File already exists. Use edit tool instead.'
- Hook is enabled by default, can be disabled via disabled_hooks
- Includes comprehensive test suite with BDD-style comments
