feat(ci): add GitHub Actions workflow for eslint-effect-ts-check

- Add lint-effect job to check.yml workflow for Effect-TS compliance checks
- Add lint:effect script to root and app package.json
- Use eslint.effect-ts-check.config.mjs for strict functional programming rules

INVARIANT: ∀ commit ∈ Commits: passes(lint_effect, commit) → Effect_TS_compliant(commit)
COMPLEXITY: O(n) where n = number of source files
