Fix workflow_call invocations being silently skipped

Add a direct_call boolean input (defaults to true) to workflow_call
so reusable workflow callers bypass the event-specific filtering gate.
Without this, callers triggered by e.g. pull_request opened would
hit the pull_request branch which requires requested_team.slug == 'claude',
causing a silent no-op.
