No production deployments exist, so there's no need for migration shims.
Remove all six backwards-compat type aliases (AgentError, SdkError,
CoreError, GraphvizError, StoreError, FabroError) and migrate ~880
callsites to use the canonical Error name directly within each crate,
or qualified imports (e.g., `use fabro_llm::Error as LlmError`) for
cross-crate references. Also fix a pre-existing absolute-path clippy
lint in fabro-server error.rs.

Add the stripped twin-github test server to the workspace, wire it through
fabro-test, and cover fabro-github's real HTTP auth and pull-request flows
with twin-backed integration tests. This also refactors the GitHub helper
entry points to take explicit base URLs so tests and callers share the same
request path.
