refactor(model-core): inject bundled capabilities snapshot from harness

- remove bundled snapshot dependency on src/generated in model-core

- make shared harness provide runtime bundled snapshot

- update guardrail and capability tests to pass explicit snapshot

Ultraworked with [Sisyphus](https://github.com/code-yeongyu/oh-my-openagent)
