Two bugs:
1. Manual 'Refresh' button didn't refresh weather/RSS before compiling.
The daily scheduler calls refresh_all_feeds + refresh_location_cache
before run_compilation; the manual trigger route called run_compilation
directly, reading a stale cache. Manual trigger now mirrors the
scheduler: refresh feeds and all configured weather locations first.
2. Navigating to WorkspaceView during a long briefing compilation caused
the workspace chat to show the briefing content. triggerNow awaits
~30-60s; on completion it called loadAll() → chatStore.fetchConversation
which overwrote the workspace's currentConversation in the shared store.
Fixed with a _mounted flag — all post-async state writes in BriefingView
are now guarded so they no-op if the component has been unmounted.
