+- **playwright: default browser channel `chrome` → forced `--browser chromium` (v2 / 1.0.1)** — `@playwright/mcp` 0.0.79 defaults to the `chrome` channel, i.e. *system Google Chrome*: on slim Linux hosts (no `/opt/google/chrome/chrome`) every tool call failed with `Chromium distribution 'chrome' is not found at /opt/google/chrome/chrome`. It went unnoticed in local testing because macOS borrowed the installed system Chrome, and `verify.js` (plain `chromium.launch`, no channel) probes the OSS build — not the one the server would actually launch. The wrapper now passes `--browser chromium` (the Chrome-for-Testing build downloaded by the postinstall hook, same as the official Docker image). Confirmed via the browser session registry: `channel: chrome-for-testing` after the fix vs `chrome` before.
