Summary

TASK-665. Two backend token-copy test files intermittently failed on some merge-queue runners and dropped queued PRs.

• The CLI child prints (node:…) [DEP0040] DeprecationWarning: The punycode module is deprecated on those runners.
• scrubFeedTokenCopies.test.js (success path, toBe('')) and migrateChatTokenCopies.test.js (failure path, exact stderr) compare the child's stderr exactly, so the warning failed them.

Fix: the CLI child in each spawn gets NODE_OPTIONS: '--no-deprecation'. The child's env only; the test process is unchanged.

• Every fail-closed assertion on the secret-echo path is unchanged (not.toContain(secretUri), not.toContain('unexpected-sensitive-argument'), and the exact failure message).
• No workflow change.
• Checked locally: node -e "require('punycode')" prints the DEP0040 line, and with --no-deprecation it prints nothing. Both suites pass (14 tests).

Walkthrough

The chat-token migration and feed-token scrubbing CLI tests now pass --no-deprecation through NODE_OPTIONS in spawned processes. The tests preserve other environment values and existing assertions.

Changes: CLI test environments

Layer / File(s)	Summary
Set subprocess warning options backend/__tests__/unit/scripts/migrateChatTokenCopies.test.js, backend/__tests__/unit/scripts/scrubFeedTokenCopies.test.js	The spawned CLI tests set NODE_OPTIONS to suppress deprecation warnings. Existing environment values and assertions remain unchanged.

- Line 184: Update the child-process environment options in the migration test
setup so NODE_OPTIONS appends --no-deprecation to any inherited value instead of
replacing it; preserve the existing MONGO_URI and other inherited environment
entries.

Tier 0 check at 256b9b0 (operator, Launch). Tests only (two script test files), so no seat gate is owed. CI is green, and CodeRabbit confirmed the NODE_OPTIONS fix at this head.
