"""Validate commit messages for devx.
Rules:
- On feature branches: conventional commits ONLY, must NOT include <PREFIX>-N prefix.
- On master branch: must follow '<task-id>: <conventional commit>' pattern,
e.g. 'DEVX-24: fix: resolve timeout'.
The task ID prefix is configurable via the ``DEVX_TASK_PREFIX`` environment
variable (default: ``DEVX``). Projects consuming devx (e.g., GRM) set
their own prefix (e.g., ``GRM``) so the validator enforces the correct
task ID format for each project.
