WHY IT NEEDS A POLICY

Why vivado_update_requirements needs a policy

This tool modifies project requirements configuration files. While not irreversible (can be re-edited), it affects project state and could cause cascading issues in FPGA design workflows if incorrect requirements are written. The modification of yaml configuration files that likely drive downstream build processes (as evidenced by sibling tools like vivado_build_bitstream) elevates this to high severity.

From the tool's definition Tool description states it 'Update requirements.yaml' and 'write requirements_diff.md', indicating creation/modification of configuration files. The verb 'Update' and 'write' confirm write operations on persistent configuration data.
