"""
Identity Injector - Injects branch identity on every prompt.
Reads from [BRANCH].id.json and outputs core identity fields.
Finds the branch root by walking up from CWD looking for apps/ or *.id.json.
When CWD is inside a project that has its own UserPromptSubmit hooks,
this provider-level hook exits silently to avoid double-firing.
Version: 1.1.0
