pi-clawa v0.2.0

Changed

• Pi is now the sole compaction owner. At 90% of the active model's context window, Clawa gets one
  same-branch memory pass to recall recent shared memories and save only genuinely new or updated
  continuity before Pi compacts normally. Legacy clawa.compaction settings no longer alter this.
• Living-document and optional image hydration is now persisted in session history at lifecycle
  boundaries, so Pi's native compaction and provider continuation rebuild the same model-visible
  branch instead of losing extension-injected context or cache continuity.
• recall now takes a fast path for recent shared memories, streams bounded session search, and
  keeps only the strongest results instead of synchronously loading broad session history.
• Worker configuration now has one strict normalization path. Duplicate IDs and malformed booleans,
  thinking levels, report modes, or extension lists fail visibly rather than changing behavior.
• message_clawa now returns a concise named delivery receipt instead of repeating the outgoing note.
• Development checks now target Pi 0.84.0.

Fixed

• Successful Pulse deliveries are checkpointed individually, so a later failed Pulse cannot replay
  work that already landed.
• Failed partial Clawas daemon starts are disposed before retry, and local comms reject malformed
  commands and response payloads at the socket boundary.
