Phase 1 — Fix scope system: new scope-resolver.ts resolves global vs
space-scoped docId prefixes. Server middleware sets effectiveSpace on
Hono context. All 18 modules updated to use dataSpace for Automerge
doc access while keeping space for display. Client runtime gets
setModuleScopes() and resolveDocSpace() for local-first scope
resolution.
Phase 2 — Seamless cross-space navigation: TabCache now tracks panes
per space:module key. OfflineRuntime maintains lazy WebSocket
connections per space. Space-switcher dispatches space-switch event
handled client-side with history.pushState instead of full reload.
Phase 3 — Spaces as layers: Layer type extended with spaceSlug and
spaceRole. Tab bar gains "Add Space Layer" picker. Canvas renders
cross-space shapes with visual indicators. Space layers persisted as
SpaceRefs via nesting API. Runtime provides getAllActiveSpaces() and
subscribeModuleAcrossSpaces() for module-level data aggregation.

The tab cache's extractContent() only collected <link> stylesheets, missing
inline <style> blocks. The canvas toolbar CSS is entirely inline, causing
unstyled toolbar when switching to the rSpace tab via tab cache.

- Tab bar state persists to localStorage per space
- Emergency synchronous localStorage fallback for beforeunload saves
- Merge Automerge full-sync instead of replacing (preserves local changes)
- Validate shape coordinates before applying (prevent NaN/Infinity)
- Save on visibilitychange for mobile browser tab backgrounding
- Add OutputPath type for module browsable content types
- Fix canvas module ID from "canvas" to "rspace" in tab-cache

Previously loaded tabs stay in the DOM and are shown/hidden via CSS.
New tabs are fetched via fetch() + DOMParser on first visit, then
cached. Switching back is instant with no network request.
