Add a category_routing block to org.yaml schema (defaults + per-workspace,
UNION semantics with per-key replace). The merged routing table is rendered
into each workspace's config.yaml at import time.
PM's system prompt loses the hardcoded security/ui/infra → role mapping
from PR #50; instead it reads category_routing from /configs/config.yaml
and delegates to whatever roles the org template lists for the incoming
audit-summary's category. Future org templates ship their own routing
without prompt churn.
Tests: 4 new TestCategoryRouting_* cases covering YAML parse, UNION+drop
semantics, deterministic config.yaml render, and empty-map handling.

Observed 2026-04-14 morning: audit crons (Security, UIUX, QA) were flowing
messages into PM per the PR #26 contract, but PM stopped sub-delegating to
Dev Lead ~10 hours ago. Meanwhile audits started opening PRs directly
(bypassing Dev Lead), and Dev Lead / BE / FE / DevOps / QA sat idle for
17+ maintenance cycles despite PRs continuing to land.
Root cause: PM's system prompt defined delegation behavior for "tasks from
CEO" but didn't explicitly treat audit summaries as tasks. PM was reading
"audit of SHA X, filed issue #N, top recommendation: fix Y" as a status
report and committing it to memory without triggering the dispatch chain.
Adds a dedicated "Audit Routing" section to PM's prompt that:
- Treats every audit summary with open issue numbers as a dispatch trigger
- Specifies routing by category (security→BE, ui→FE, infra→DevOps, qa→QA)
- Requires parallel `delegate_task_async` when issues span categories
- Makes clean-cycle acks the only no-op case
This turns PM from a receptionist into a dispatcher — which was the
original intent of the audit-routing contract in #26.
Aligns with the north-star goal (keep the team running 24/7): dead idle
windows when audits had live issue numbers is a defect in orchestration,
not a quiet period.
