Add example standards, template and CI format checks

[dazzatronus]

Nothing enforced the repo's own .prettierrc, and the four examples had drifted apart on naming, declared Node floors and format scripts. This adds the enforcement and writes the conventions down.

What changed

• STANDARDS.md — credential handling, failure behaviour, README shape, runtime-version rules, and what to check before opening a pull request.
• examples/_template/ — copy it to start a new example, so structure comes for free rather than arriving as a review comment.
• .github/workflows/check.yml — prettier --check and ruff check on every pull request.
• ruff.toml — line length 88, plus pyflakes and bugbear. Passes trivially until an example ships Python.
• .claude/settings.json — points coding agents at STANDARDS.md when a session opens in this repo.

Reviewer notes

• examples/reelestate/package.json declared "name": "rapidreels". Fixed.
• Added engines to both Next examples (>=20, matching .nvmrc) and a format script to instagram-ai-video.
• Four pre-existing files were reformatted so --check passes: instagram-ai-video/index.js, both postcss.config.js, and reelestate/pages/_document.tsx. No behaviour change.
• .env.local.example in the Next examples is deliberate, not drift — Next loads .env.local. STANDARDS.md states that exception.

Verify

npx prettier@3 --check .   # All matched files use Prettier code style!
ruff check .               # All checks passed!
