Lattice AI v4.0.1

Lattice AI v4.0.1 — Digital Brain Platform Maintenance

Status: GitHub Release only. This release builds and validates artifacts for
commits on main after tag v4.0.0; it does not publish to PyPI, npm, the VS
Code Marketplace, or Open VSX.

v4.0.1 is a maintenance release that closes the post-v4.0.0 implementation
delta on main without reusing the v4.0.0 version number.

Included since v4.0.0

• Durable async run executor for agent/workflow runs: persisted queued/running/
  final states, realtime SSE progress, cooperative cancellation, and startup
  reconciliation of orphaned active runs.
• Stable user UUID migration, policy-backed admin authorization, local
  invitation tokens, and SQLite-backed Workspace OS state with JSON
  compatibility mirroring.
• Complete /app SPA parity and legacy UI retirement: token-native account,
  profile, password, workspace/org administration, invitations, snapshots/time
  machine with merge-restore, activity/presence, run approvals/cancellation,
  workflow trigger configuration/status, Brain Network pairing/push, chat
  context trace, and Knowledge Graph provenance coverage.
• en/ko i18n runtime coverage for routes, shell text, and parity views, guarded
  by frontend lint.

Release only.
