ModelRole collapses to "primary": every role (main, tool selector, memory
agents, subagents, summarizer) resolves to the snapshot's frozen primary
model, per design 6.1/8.3 — users typically configure a single usable LLM,
so compile-time auxiliary bindings were bypassing run snapshots and
mis-attributing usage. Legacy auxiliary keys in stored snapshots, registry
JSON, and thread metadata are tolerated on read and dropped.
BREAKING CHANGE: ThreadModelSelection no longer carries an auxiliary ref;
snapshot selection_hash is computed over {primary, reasoning_effort} only;
ConfigurableModelMiddleware(role="auxiliary") is rejected.

Graph construction no longer raises on a bootstrap registry: build paths
bind a shared RegistryNotReadyChatModel placeholder that fails every call
with MODEL_REGISTRY_NOT_READY, so langgraph dev serves the Config API for
first-time configuration while run creation stays forbidden.
Run snapshot binding no longer compares configurable
'workspace_deployment_id' (the workspace-isolation scope id) against the
snapshot's issuing deployment — a mismatch that made every BFF run fail
with SNAPSHOT_NOT_FOUND. SnapshotService.get_for_run verifies thread_id
equality plus membership in the platform-registered deployment set
(local_deployment_id + webui_delegation_public_keys entries).
Blocking I/O moved off the event loop for langgraph dev's blockbuster:
Config API authentication (store mkdir/chmod, config.yaml read, jti
registration) and the message-budget snapshot read now run in threads,
with the immutable snapshot cached per run.

- Remove legacy provider profiles, admin-token auth, /model command,
model picker widget, and config.yaml LLM fields (design doc section 10)
- Wire CLI/channels/cron and async sub-agents through the local snapshot
entry; run creation rejects model config outside runtime_snapshot_id
- Add periodic run-snapshot TTL cleanup to the config service lifespan
- Isolate tests from the real config dir and activate the registry where
run/model paths fail closed in bootstrap
