Introduces three new weekly agents that form a triage→plan→build pipeline:
- proposal-triage-agent: evaluates proposals, dead ends, and coverage gaps;
produces prioritized backlog in src/backlog/BACKLOG.md
- plan-agent: creates concrete implementation plans from top backlog items
in src/plans/PLAN-*.md
- builder-agent: executes approved plans, makes code changes, verifies
acceptance criteria
Also includes:
- Architecture proposal document in docs/proposals/
- Seeded initial backlog with 11 items from diagnosed dead ends
- Updated roster.json and weekly-scheduler.md (24 weekly agents)
- All three validators pass (prompt-contract, scheduler-roster, flow-parity)
