The extension now reports which playwriter version it was built with via a
`?v=` query param on its WebSocket connection to the relay. The relay stores
this and exposes it in `/extension/status` and `/extensions/status` endpoints.
CLI and MCP compare the extension's bundled version against their own VERSION.
If the extension was built with a newer playwriter, a warning is shown:
Playwriter 0.0.60 is outdated (extension requires 0.0.62).
Run `npm install -g playwriter@latest` or update the playwriter package.
This is fully backward compatible:
- Old extensions without `?v=` get `playwriterVersion: null`, no warning
- No WS protocol changes (version is in URL query params)
- Warning fires once per executor/session lifetime
Flow:
vite build reads playwriter/package.json → injects __PLAYWRITER_VERSION__
→ extension sends ?v=X.Y.Z on WS connect → relay stores in ExtensionInfo
→ /extension/status returns playwriterVersion → CLI/executor checks & warns
