Phase 4 complete: client data cache + plan update
- Add page data cache in orchestration.sx (30s TTL, keyed by page-name+params)
- Cache hit path: sx:route client+cache (instant render, no fetch)
- Cache miss path: sx:route client+data (fetch, cache, render)
- Fix HTMX response dep computation to include :data pages
- Update isomorphic-sx-plan.md: Phases 1-4 marked done with details,
reorder remaining phases (continuations→Phase 5, suspense→Phase 6,
optimistic updates→Phase 7)
