Remove .playwright-mcp snapshots

.playwright-mcp/page-2026-08-18T15-39-54-362Z.yml and .playwright-mcp/page-2026-08-18T15-40-23-711Z.yml are accessibility snapshots dumped by the Playwright MCP server during a browsing session. They sit in the working tree, hidden from git only by a global ignore file, and capture the "Cleanup Magazine components" navigation from the magazine era.

Tasks

• Delete the .playwright-mcp/ directory
• Add .playwright-mcp to the project .gitignore so clones without a global ignore do not pick it up
