Fix cleanup run scheduling context

[chubes4]

Summary

• Pass the active agent slug when DMC schedules workspace cleanup runs so Data Machine accepts the queued system task.
• Treat empty scheduler results as explicit failures instead of returning unusable cleanup-run-0 IDs.
• Add smoke coverage for agent-context scheduling and empty-schedule error handling.

Testing

• php -l inc/Abilities/WorkspaceAbilities.php
• php tests/smoke-workspace-cleanup-run-context.php
• php tests/smoke-worktree-cleanup-cli.php

AI assistance

• AI assistance: Yes
• Tool(s): OpenCode (GPT-5.5)
• Used for: Diagnosed the cleanup scheduling failure, drafted the code/test changes, and ran local verification. Chris reviewed/approved the release and merge path.
