Good idea

> <https://github.com/discourse/discourse-mcp/pull/19>
>
> Updates minimum Node.js requirement from 18 to 24.
> 
> The \`generate-user-api-key\` …tool uses \`RSA\_PKCS1\_PADDING\` which is no longer supported in Node.js versions below 24, causing runtime errors during API key generation.
> 
> \*\*Changes:\*\*
> \- Bump \`engines.node\` to \`\>=24\` in package.json
> \- Update version to 0.1.11
> \- Add breaking change entry to CHANGELOG.md
> 
> Fixes https://meta.discourse.org/t/discourse-mcp-user-api-key-generator-error-nodejs-20/390073
