ix-mcp Python sessions ship playwright with browsers wired

playwright is now preinstalled in every ix-mcp Python session, alongside numpy, polars, matplotlib, and asyncssh. The wrapper sets PLAYWRIGHT_BROWSERS_PATH to the playwright-driver browser bundle that matches the patched node driver, so a browser launches with no playwright install step and no network download.

Use the async API so it shares the session event loop:

from playwright.async_api import async_playwright

p = await async_playwright().start()
browser = await p.chromium.launch()
page = await browser.new_page()
await page.goto("https://example.com")
print(await page.title())
await browser.close()

Chromium and Firefox are the reliable engines under Nix; WebKit is known to be flaky. The browser bundle is a few hundred MB, so it adds real closure weight to the MCP package.
