v0.6.1

Fixed

• The upstream Playwright MCP failed to spawn whenever PlayGuard itself was not
  the project root — under npx, a global install, or any hoisted layout. It
  was located by shim (node_modules/.bin/playwright-mcp) with a fall back to
  the bare command name, and in those layouts the shim sits in a directory that
  never reaches the child process's PATH, so every browser tool failed with
  "playwright-mcp.cmd is not recognized". It is now resolved through Node's
  module graph and run with the node binary already in use, which does not
  depend on PATH or on where the package was installed.
