defpage is already portable: server executes via execute_page(),
client via try-client-route. Add render plan logging to client
routing so console shows boundary decisions on navigation:
"sx:route plan pagename — N server, M client"
Mark Phase 7 (Full Isomorphism) as complete:
- 7a: affinity annotations + render-target
- 7b: page render plans (boundary optimizer)
- 7e: cross-host isomorphic testing (61 tests)
- 7f: universal page descriptor + visibility
7c (optimistic updates) and 7d (offline data) remain as future work.
