Generate RuboCop-clean Ruby SDK files

[ChiragAgg5k]

Summary

• make Ruby templates emit RuboCop Layout-clean source and packaging files without post-generation formatting
• ship .rubocop.yml with Layout cops only, 4-space indent matching sdk-for-ruby house style, and a 200-character line limit
• normalize generated method signatures, hashes, comments, and whitespace directly in Twig
• enforce check-only RuboCop 1.90.0 validation for the Ruby SDK in CI

before: generate -> run formatter -> commit formatting changes
after:  generate ----------------> formatter-clean SDK

Part of #1813.

Ruby has no inherited/child SDK targets. REST/GraphQL/skills/editor plugins are out of scope.

CI note (web client on d6ea4a9)

Validation job web (client) failed in ~20s on php example.php web client, before any npm step:

Generating SDK: web (platform: client)
Error: Invalid JSON: Syntax error on .../vendor/utopia-php/openapi/src/Parser.php:57

This PR does not change Web templates. The same job on later main (#1842) was green. Cause: getSSLPage() returned non-empty invalid JSON from the live specs fetch (Parser.php:57 json_decode(..., JSON_THROW_ON_ERROR)). Rebased onto main (328cc07fa, #1842) and re-verified locally. No retry/sleep/continue-on-error added.

Greptile review on d6ea4a9 was 5/5 with no line comments.

Test plan

Ruby (#1813):

• rm -rf examples/ruby && php example.php ruby server — pass (1/1 after rebase)
• (cd examples/ruby && rubocop) — 405 files inspected, no offenses (1/1)
• rm -rf examples/ruby && php example.php ruby client && (cd examples/ruby && rubocop) — 120 files, no offenses (1/1, pre-rebase)
• composer lint-twig — 0 errors
• vendor/bin/phpcs src/SDK/Language/Ruby.php — pass

Web (the red CI job, after rebase):

• Fetch open-api3-1.9.x-client.json and json_decode — valid JSON (1/1)
• rm -rf examples/web && php example.php web client — pass (1/1)
• (cd examples/web && npm ci && npm audit && npm run format:check && npm run lint && npm run analyse && npm run build) — pass (1/1)

Console generation (php example.php ruby console) still hits a pre-existing Lint/Syntax failure in console_variables.rb: several _APP_* schema names collapse to the same snake_case keyword. That collision exists on main and is not introduced here.

Greptile Summary

The PR updates Ruby SDK templates to emit RuboCop Layout-clean code directly and adds generated RuboCop configuration plus CI validation.

• Adds a Ruby-specific rtrimLines Twig filter and emits .rubocop.yml with generated SDKs.
• Reformats generated Ruby package, client, model, service, and support templates.
• Adds pinned RuboCop validation to the Ruby generation workflow.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains.
