Agent Observer 0.5.0a12

Accepted optional Mesh state reader for Codex and Claude interactive observation. Local and fleet cached snapshots and replacement-state watch are independently packaged and validated on Snap and Starship. API 2, snapshot/watch 4 and Service 2 are unchanged.

The attached wheel is the exact accepted artifact, SHA-256 e292e689a1dd1b32fec1a10617330cf32777c8e347d98512c2c0c3fabfd39568, built from e55825e. The manifest records required native contracts. Install the attached compatible Mesh Plus a4 wheel separately for mesh commands; this release does not imply PyPI availability, provider policy, collection-service replacement or frontend rollout.
