Greptile Summary

This PR fixes the broken Yarn APT repository present in the mcr.microsoft.com/devcontainers/java:1-21-bullseye base image by removing /etc/apt/sources.list.d/yarn.list before running apt-get update, and migrates the devcontainer config from a bare image reference to a Dockerfile build. It also bumps the Android platform and build-tools from 35 → 36, removes the redundant Java devcontainer feature, and delegates Node.js installation to the ghcr.io/devcontainers/features/node:1 feature (commenting out the previous fnm-based install). All remaining findings are P2.

Confidence Score: 5/5

Safe to merge — the core fix is correct and all findings are minor style suggestions (P2).

No P0 or P1 issues found. The broken-yarn-repo fix is straightforward and correct. The remaining comments are about dead ARG/package and a redundant pnpm install, none of which affect runtime correctness.

No files require special attention.
