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.
