Fixes Svelte 5 ssr_context.r error caused by store subscriptions
running during server-side rendering without a component context.
The pilot is a client-side SPA that requires browser APIs and auth.

Replace writable/derived stores with $state objects in .svelte.ts
files. The old store pattern caused ssr_context errors and onMount
not firing with ssr=false. Using $effect instead of onMount for
initialization resolves the client-side hydration issue.

…oard shortcuts

Migrate from Tailwind v3 to Tailwind v4 with basecoat-css component library.
Major UI overhaul matching the Rails reference implementation:

- Basecoat sidebar with collapsible state, chat list, nav items
- Kanban board with vim-style navigation (hjkl/arrows), multi-select (x),
  bulk actions (run/delete/done), drag-and-drop, context menus
- Task cards simplified to match Rails: title + spinner + badges + timestamp
- Task detail modal with two-pane file viewer (preview/source/diff tabs)
  for tasks with artifacts, compact single-column for simple tasks
- Native <dialog> elements for all modals with basecoat styling
- Chat panel with quick actions that send messages directly
- Keyboard shortcuts: Cmd+K search, N new task, Cmd+Enter execute,
  Cmd+Delete delete, Shift+arrows move tasks, [ ] toggle panels, ? help
- UI state persistence (sidebar, chat panel, board width, focus position)
- Polling reduced to 5s for near-realtime kanban updates
- All button classes converted to basecoat compound format (btn-sm-ghost etc)

Streaming duplication: A race condition in the WebSocket close handler
caused stale sockets to overwrite the current taskWs reference to null,
triggering reconnects that created duplicate connections. Both connections
fed text deltas into the same store, doubling every phrase. Fixed by
checking `taskWs === ws` in all event handlers to ignore stale sockets,
and clearing the reference BEFORE calling close() in disconnectTaskChat.

Message persistence: Messages were cleared on every disconnect, so
reopening the modal lost conversation history. Now messages are only
cleared when switching to a DIFFERENT task — the server restores them
via cf_agent_chat_messages on reconnect to the same task.

Modal overflow: TaskChat containers used shrink-0 with fixed heights,
pushing content past the modal bounds. Changed to flex-1 with min-h
constraints so the chat participates in flex layout properly.
