feat(mcp): add display title + favicon to server.json so directories show a real listing

- title: "Timebook" — display name third-party MCP browsers (Smithery, mcp.so) show alongside the description.
- icons: SVG favicon hosted at https://usetimebook.com/favicon.svg (image/svg+xml, sizes "any"). Verified live with HTTP 200 + correct mime.
- Validated against the canonical 2025-12-11 server.schema.json — passes Draft 7.

Note: server.json `version` stays 0.2.0 here on purpose — the existing CI step "Sync server.json version to released tag" rewrites it to match the released git tag before publishing to the MCP Registry.
