WHY IT NEEDS A POLICY

Why link_task_to_commit needs a policy

This tool creates or modifies relational data (task-to-commit associations) in a reversible manner. The operation is described as creating an 'audit trail' and performing upserts (update or insert), which are Write operations. While it involves version control metadata, it does not destructively delete data, execute code, move funds, or trigger external processes.

From the tool's definition Link a git commit SHA to a task. Creates an audit trail: task → commits. Upserts on same task+sha.
