fix(process): add architect Safe Exit for deferred decisions, clean hedging language

- Add Safe Exit section to architect spec: when a decision genuinely can't
  be made, mark OQ as deferred(scope) with concrete blocking condition,
  create blocker task, move on
- Add anti-patterns #10-#11 covering hedging synonyms (feature extension,
  additive, not a v1 blocker, for now, resolved with escape hatch)
- Add hedging audit to architect self-review checklist
- Clean hedging language from resolved OQs (OQ-04, OQ-13, OQ-14, OQ-16)
- Reclassify OQ-32 and OQ-41 as deferred(scope) with blocking conditions
- Add deferred(scope) status to OQ format in sdd_process.md
