uBix Vault v0.2.0-beta.3

Third beta. The /ui/ web console gains full read/write management.

Added

• Web console management — beyond read-only:
  • KV v2: create/edit secrets (→ new version), version history, read a specific version, per-version soft-delete / undelete / destroy (inline confirm).
  • ACL policies: list, read, create/edit (JSON or HCL), delete.
  • Tokens: mint a child token scoped to policies with an optional TTL.

Same posture: token in header (no cookies), strict CSP, textContent rendering, every write an audited /v1 call.

Pre-release. Not production-hardened; no external security review. For production, use HashiCorp Vault or OpenBao.
