Gameplane modules

OCI game templates for Gameplane. Each <name>/ folder holds module.yaml, template.yaml, README.md and optional icon.png, specs.md, samples/. build.sh push publishes them; validate.py preflight-checks them in CI.

Translations

A module can ship translations in <name>/locales/<tag>.json (flat JSON, message id to ICU message).

• locales/en.json is the English reference. It is generated, never hand-written: gp-module i18n extract <name>. It is not pushed to the registry.
• To add a language, copy en.json to locales/<tag>.json (a valid language tag such as de or pt-BR), translate the values, keep the placeholders, then run gp-module i18n stamp <name> to record the source hashes.
• build.sh push adds one layer per locales/<tag>.json (except en.json).
• CI runs i18n-check --module on every module with a locales/ folder: ids must match the template, placeholders must match English, and en.json must not drift from the template.
