Docs: tighten devcontainer JSON + stable Codespaces port setup

02ez · Copilot · web-flow · commit 108d1a2f4a31 · 2025-08-30T13:38:24.000-07:00
- Convert examples to strict JSON (no comments/trailing commas).
- Recommend forwardPorts: [4000] and `gh codespace ports visibility 4000:public -c "$CODESPACE_NAME"`.
- Add quick validation: `jq -e .` and `npx @devcontainers/cli validate`.
- Scope is docs only; happy to adjust to house style.
