feat(core-consent): extend generator with consent template + fix withCapture brand propagation

- Add consent to CORE_PACKAGE_GENERATORS in turbo/generators/config.ts so
  pnpm turbo gen core-package consent is a valid command (not hand-rollable)
- Create turbo/generators/templates/core-package/consent/ mirroring the
  analytics template shape (AGENTS.md, package.json, tsconfig, turbo, vitest,
  eslint, src/index.ts scaffolds)
- Regenerate packages/core-consent/ from the new template (replaces the
  previous hand-rolled attempt that violated the generator-first rule)
- Add __consentChecked to withCapture PROPAGATED_BRANDS so the brand bubbles
  through the full withSpan→withCapture wrapper chain to the outermost binding
  that assertFeatureConformance reads
