* feat: store and expose hostContext in App class
Fixes#129 - The App class now stores the initial hostContext received
during initialization and exposes it via getHostContext().
Changes:
- Add _hostContext private property to App class
- Store result.hostContext in connect() method
- Add getHostContext() getter method (parallel to getHostCapabilities())
- Update onhostcontextchanged setter to merge partial updates into
stored context
- Add default notification handler to update context even when
user hasn't set onhostcontextchanged
This enables apps to:
- Access toolInfo immediately after connection (only in initial context)
- Render with correct theme/locale without waiting for first notification
- Synchronously access viewport, timezone, and other initial state

* fix: use sendHostContextChange for partial update accumulation test
Address PR review feedback: The test was using setHostContext with full
context spreads which didn't clearly demonstrate partial update
accumulation. Now uses sendHostContextChange directly to send truly
partial updates (only theme, then only viewport), making it clear
the App correctly merges multiple partial notifications.
