Module loader 

Layered loader that composes the final SubagentProfileRegistry.

Layers (each later one overrides earlier entries by id):

1. Built-in profiles (super::builtin::builtin_profiles).
2. User global config: <bamboo_data_dir>/subagent_profiles.json.
3. Project-level config: <workspace>/.bamboo/subagent_profiles.json (only loaded when a workspace path is provided).
4. Env override: BAMBOO_SUBAGENT_PROFILES_FILE=<path> if set.

Missing files are silently skipped; malformed JSON returns LoaderError::Parse so misconfiguration is surfaced loudly.

Enums

Constants

CONFIG_FILE_NAME
