#4116: Update Dockerfile to node 24

**Subject**: chore(docker): Upgrade Node.js base image to v24 (Active LTS) **Description**: This PR upgrades the application runtime environment from Node.js 22 to Node.js 24. Transitioning to the latest Active LTS version ensures the following benefits: **Security Posture**: Ensures the container includes the latest security patches and mitigations for CVEs present in older runtimes. **Performance**: Leverages the updated V8 engine for better execution speed and improved memory management (garbage collection). **Long-Term Support**: Aligns the infrastructure with the official Node.js support lifecycle, preventing technical debt accumulation. <!-- greptile_comment --> <h2>Greptile Overview</h2> <h3>Greptile Summary</h3> This PR updates the Docker base image from `node:22-bookworm` to `node:24-bookworm` to align the container runtime with Node.js 24 (Active LTS). The rest of the Dockerfile (Bun install, pnpm/corepack usage, build steps, and switching to the non-root `node` user) remains unchanged and continues to define the build/runtime environment for the app. <h3>Confidence Score: 4/5</h3> - This PR is safe to merge with low risk, as it is a straightforward base image bump. - The diff only changes the Node base image tag; the only concrete issue found is a stale comment referencing the old image version. Runtime/CI compatibility with Node 24 should still be validated in the usual pipeline, but no code-path changes are introduced here. - Dockerfile (minor comment mismatch) <!-- greptile_other_comments_section --> _{(2/5) Greptile learns from your feedback when you react with thumbs up/down!} <!-- /greptile_comment -->
