Remove unused eslint-disable directives and update CLAUDE.md

- Remove unused @typescript-eslint/no-deprecated disable from eslint.config.ts
  (the directive was reporting as unused in CI)
- Remove no-var from context.ts disable (not needed - TypeScript parser handles it)
- Update CLAUDE.md to require running `yarn run eslint --report-unused-disable-directives`
  before every commit to match CI's exact check

This ensures local linting matches CI behavior exactly.
