Vibe Codr v0.7.9

Added

• Canonical turn, message, and part identities now carry lifecycle, revision,
  timing, source, and output-path metadata across the engine protocol, persisted
  history, reconnect hydration, diagnostics, and Desktop rendering.
• Desktop drafts, attachments, and prompt history are isolated per project and
  session; accepted prompts can be recalled with Up/Down without leaking into a
  different conversation.

Improved

• Completed Desktop turns now use one lossless Work disclosure and an always
  primary final answer. Actual turn duration replaces inferred tool time, and
  long silent work gets a compact non-terminal status instead of transcript
  noise.
• Tool calls have explicit queued, running, waiting-for-approval, succeeded,
  failed, and cancelled states, with correlated approvals and a deterministic
  repeated-failure circuit breaker.

Fixed

• Session saves commit immutable, hashed generations through one atomic
  manifest, recover the previous complete generation after corruption, and
  safely prune stale generations. Renderer collections are bounded and stale
  events from superseded turns no longer mutate the active turn.
• Multi-command UI actions cross the host boundary as one ordered command batch,
  and engine errors no longer falsely mark a still-running queue idle.
