chore(gitignore): ignore .playwright-mcp/ and inspect/ scratch dirs

Both directories are generated by tooling that any aiolabs site
forked off the boilerplate is likely to run:

- .playwright-mcp/  — written by the Playwright MCP server (snapshots,
  console logs) every time it drives a browser. Lives in main now via
  .mcp.json so this gitignore entry belongs here too.
- inspect/          — convention for a scratch folder holding
  screenshots, style dumps and other visual-QA artifacts produced
  during dev. Not source of truth for anything.
