Prometheus Entity Management 3.0.3

Coordinated stable patch release. Supersedes 3.0.2 on the npm latest and next tags.

Fetched entity lists, lifecycle metadata, and list projections are now ingested in a single atomic graph publication. The core and React list paths previously published once per returned row, so a fetch of N rows produced N graph writes and N render passes; subscribers could also observe a partially populated list between writes. Both paths now publish once per fetch.

All twelve @prometheus-ags packages are public at 3.0.3, published with pnpm publish so that pnpm workspace: specifiers are rewritten to real semver ranges while packing. Every package manifest was re-read from the registry after publication to confirm no workspace: protocol leaked. entity_graph_flutter remains at 3.0.0 on pub.dev and is unaffected by this release.
