v0.3.1-beta.0 - Adapter config hardening

Summary

CEWP v0.3.1-beta.0 continues the v0.3 adapter foundation work with adapter config hardening, doctor visibility, init template support, and CodeGraph workflow hygiene.

This release still supports only the codex-exec provider. External provider support is not implemented yet.
