[codex] Extract DNA runtime wiring

[elkimek]

Summary

• Add a DNA runtime adapter for shell/global integration points: SNP cache publication, debug logging, navigation, sidebar refresh, import-running guard, file-picker bridge, pending import state, delete confirmation, and legacy window binding publication.
• Remove direct browser-global access from js/dna.js while preserving the legacy exported browser surface.
• Lower the quality guardrail window-reference baseline from 613 to 589 and include dna-runtime in service worker/typecheck coverage.

Validation

• ./run-tests.sh
• npm run quality
• npm test
• npm run typecheck
• npm run typecheck:checkjs
• npx playwright test tests/playwright/dna-browser-coverage.spec.js --workers=1

Greptile Summary

This PR moves DNA browser wiring into a runtime adapter. The main changes are:

• New js/dna-runtime.js adapter for shell hooks and legacy globals.
• js/dna.js now delegates global access through the adapter.
• Delete and import guard paths now report failure states through adapter contracts.
• The new module is included in service-worker and typecheck coverage.
• Runtime-focused tests were added for the extracted behavior.

Confidence Score: 5/5

This looks safe to merge.

No blocking issues found in the changed code.

T-Rex Logs

What T-Rex did

• Compared the initial DNA Runtime wiring baseline by examining the before snapshot.
• Checked the after DNA Runtime wiring snapshot and confirmed the head revision wiring, 21/21 passing in DNA Runtime Adapters, and exit code 0.
• Inspected the pre-change quality guardrail output and verified 613/613 window global references, passing typechecks, absence of dna-runtime.js, and no coverage entries.
• Verified the post-change quality guardrail output, including 589/589 references, exit code 0 for guardrail checks, and the inclusion of dna-runtime.js in service-worker.js and related config/tests files.
