refactor(contracts): drop unused FOLD_SCREEN_COORDINATE_SPACE mirror from fold-runtime

[thymikee]

Removes the unused FOLD_SCREEN_COORDINATE_SPACE mirror in fold-runtime.ts; device-rotation.ts stays the single declaration. All importers (facades/device.ts, platform-apple/src/foldable/pose.ts, src/commands/system/index.ts) already read it via @agent-device/contracts/device. The remaining fold-runtime.ts import is type-only, so its eager closure is unchanged. fallow audit --base origin/main is clean.

Looks good at 7b3fcc3. The PR only deletes an unused constant from fold-runtime.ts. Nothing on the PR head imports it, and the canonical FOLD_SCREEN_COORDINATE_SPACE in device-rotation.ts stays.

The failing Smoke Tests job reports "Daemon lock is held by another process" in the iOS runner preflight. This diff does not touch daemon startup or locking, so the failure looks unrelated. Please re-run Smoke Tests. There are no conflicts, and no code change is needed.
