v0.2.3

Fixed

• npm install fails with "openclaw.extensions is empty": Renamed plugin id from memory-graphiti to openclaw-memory-graphiti so it matches the idHint derived from the npm package name (@contextableai/openclaw-memory-graphiti). This allows restoring openclaw.extensions: ["./index.ts"] in package.json — the previous workaround of emptying the array caused the installer to reject the package. Updated all references: manifest, plugin registration, service id, log prefixes, config error messages, test expectations, path references (extensions/openclaw-memory-graphiti), and documentation.
