v0.2.4

• Track memory and deterministic, project-owned engineering knowledge keep
  work resumable across provider replacement without treating chat history or
  generated summaries as authority.
• Versioned project agent contracts make process upgrades explicit, preserve
  local policy, prevent silent downgrade, and decouple workflow revisions from
  ordinary Fairway binary updates.
• Assurance profiles and signed/offline evidence packages strengthen
  restricted-environment readiness while keeping certification, legal,
  export-control, and independent-assessment claims outside Fairway authority.
• Release validation now uses bounded behavioral synchronization instead of
  scheduler-sensitive SSE timing assumptions on the macOS signing runner.
• Release assurance records the version of the exact pinned GoReleaser
  executable that built the signed candidate archives.
• Release-assurance checksums are portable and reference only the published
  asset basename, never a runner-local build path.
