New tool for capturing ad-hoc work done outside formal workplans.
Finds or creates a persistent 'interactive-<repo>' workstream for the
repo, creates the task, marks it done, and records a token event using
the three-tier logic — all in a single call.
Seeded two example events on interactive-the-custodian:
- Three-tier token recording on task done (8000/3500)
- Add record_interactive_task MCP tool (4500/1800)
