chore: release v0.7.0

[yepzdk]

[0.7.0] - 2026-05-12

Fixed

• Browser feedback no longer goes to a stale session bucket when the widget bundle is cached across MCP restarts (Browser feedback lost when widget.js is cached with a previous MCP session ID #46). The session ID is now read from the script tag's ?session= query at runtime instead of being baked into widget.js at serve time, so a cached bundle can never carry a stale session.
• /widget.js is served with Cache-Control: no-store so browsers cannot reuse a previous bundle.
• WebSocket connections that arrive with an unknown session ID are auto-rebound to the live session when exactly one MCP session is registered, or rejected with a session_invalid message (and the widget shows a visible reload banner) when the server can't safely guess.
• Pending and ready feedback queues are now persisted to disk (os.tmpdir()/claude-browser-feedback/<sessionId>.json) and rehydrated on server boot, so feedback survives crashes and restarts.

Added

• get_pending_feedback, get_connection_status, and /status now surface orphan feedback buckets (feedback filed under a session ID that no MCP session is listening for), and auto-rescue them into the current session when it is the only one registered.
