robot 0fc01646ac perf(ci): use pre-built container image for Android builds ...

- Add .devcontainer/ci.Dockerfile: bakes Flutter, JDK 17, Android SDK,
  and flutter precache --android into a single Docker image (~2GB, built once)
- ci.yml: build-android uses kryz-ci:latest container — removes 8 redundant
  SDK download steps (Java 17, Flutter, Android SDK, precache, licenses)
  that account for ~35-40 min of the 40-min container spin-up time
- release.yml: build-android uses kryz-ci:latest container — same reduction
  from 13 steps to 8. Also fixes hardcoded 'token ***' -> '$GITEA_TOKEN'
- devcontainer.json: simplified postCreateCommand (removed venv, pip, claude)
  and cleaned up invalid JSON (comments, empty mounts array)

Estimated impact: 40min -> 5-10min first run (with pre-built image),
~2-3min subsequent runs (Docker layer caching)
