Release QA gate broken: ESLint config error (`jest/globals` unknown environment key)

[meharajM]

Summary

npm run lint fails immediately due to ESLint config incompatibility:

Environment key "jest/globals" is unknown

Environment

• Date: 2026-06-01
• Command: cd ContextEngine && npm run lint

Actual output

• ESLint 8.57.1
• Error path: .eslintrc.js » @react-native/eslint-config#overrides[4]

Impact

• Release checklist cannot enforce lint gate.
• QA pipeline is partially blind to static issues.
• This is already listed as known operational limit in app-behaviour.md, but remains unresolved.

Suggested fix direction

• Update ESLint/Jest env integration to compatible versions.
• Ensure jest/globals env is recognized by current ESLint stack.
• Add a CI check to prevent config drift.

Acceptance criteria

• npm run lint exits 0 on a clean checkout.
