Integrate `websocket-stream` to handle MQTT broker upgrades in the
CLI and add granular connection status tracking to the UI.
- Add `websocket-stream` dependency
- Update CLI to use `websocket-stream` for socket upgrades
- Enhance `journalStream` store with `connectionStatus` and
`connectionError` states
- Add visual connection status indicators to `App` and `JournalPanel`
Refactor the journal server to run over WebSockets on the existing
HTTP server instead of a separate MQTT TCP port. This removes the need
for a separate port configuration and simplifies the connection flow
by auto-connecting to the current host.
- Remove `--mqtt-port` CLI option
- Attach Aedes broker to the HTTP server via WebSocket upgrade
- Update UI to remove manual broker URL and player name inputs
- Add "Content Source" access from the sidebar
- Update JournalPanel to auto-connect to the local server
Implement a journal server that uses an Aedes MQTT broker to
persist stream messages to JSONL files and manage session metadata
via a manifest.
- Add `aedes`, `mqtt`, and `zod` dependencies
- Implement `createJournalServer` in `src/cli/journal.ts`
- Integrate journal server into the `serve` command
- Add `--mqtt-port` option to the CLI
- Add session lifecycle management (create, update, delete) via
retained MQTT topics
