zouk v1.12.0

Internal: adopted humane-swift v0.9.3

ScanEntry.humanSize/timeAgo(relativeTo:) now call Humane.humanSize/Humane.distanceInTime instead of the retired Humane.SizeFormatter/Humane.TimeFormatter types — humane-swift v0.9.3 collapsed those into one enum Humane and renamed the old two-argument timeAgo to distanceInTime. timeAgo(relativeTo:) keeps its own explicit clock parameter (needed for ScanEntrySpec's fixed-time tests), so it stays on distanceInTime rather than the new one-argument timeAgo convenience. Output is byte-identical to before.

Release notes now come from this file (docs/releases/vX.Y.Z.md) instead of GitHub's auto-generated commit log — .github/workflows/release.yml's "Publish release" step reads it via --notes-file.

No other user-facing changes.
