metaharness pin drift — a pinned dependency is behind npm latest

The metaharness pin-drift watcher found a pin whose range no longer
admits the current npm release. Bump the range in
`v3/@claude-flow/cli/package.json` (and `MH_DARWIN_PIN` in
`distill-oracle.ts` if darwin moved), then re-run the guard.

Start with v3/@claude-flow/cli/package.json and inspect the metaharness pin-drift guard output in the issue. Check distill-oracle.ts for MH_DARWIN_PIN, update the stale Darwin pin consistently if needed, then re-run the guard. Done means the reported stale pin is resolved and the guard passes.
