Implement v0.6-1.0: shortcuts, format, export/import, splitter, timing, APQ

- v0.6: matchShortcut + format(); Cmd+Shift+Enter/W/F + Cmd+Alt+arrows
- v0.7: SessionStore.exportAll/importTabs with version-1 validator
- v0.8: Splitter component + four resize handles persisted under layout.*
- v0.10: createApqFetcher (HTTP-only) wrapping shared http-body helpers
- Drop .svelte re-exports from index.ts for multi-entry JSR/npm publishing
