Subject: [PATCH] fix(tools): wire PermissionEnforcer into execute_tool
 dispatch path

The review correctly identified that enforce_permission_check() was defined
but never called. This commit:

- Adds enforcer: Option<PermissionEnforcer> field to GlobalToolRegistry
  and SubagentToolExecutor
- Adds set_enforcer() method for runtime configuration
- Gates both execute() paths through enforce_permission_check() when
  an enforcer is configured
- Default: None (Allow-all, matching existing behavior)

Resolves the dead-code finding from ultraclaw review sessions 3 and 8.
