Eric Traut e1b23086ac Restore saved threads when the managed daemon restarts (#44314)
## Why

Saved threads need to resume after a managed daemon restart so active goals can continue without waiting for a client to reconnect.

## What changed

- Consume the recovery snapshot at startup and restore threads in the background through the shared cold-resume path.
- Trigger idle lifecycle work without attaching a client subscription, and leave already-loaded threads untouched.
- Continue recovery after individual thread failures and abort background recovery during shutdown.

## Testing

Extend the daemon restart integration test to verify goal continuation before client reconnection, restored conversation history and tools, idle-thread restoration, and recovery snapshot consumption. Include malformed snapshots and an invalid thread ID.

User verification cancellation (experimental)

Local UI clients can cancel a native user-verification RPC by sending userVerification/cancel with {requestId} and the experimentalApi opt-in. The result is an empty acknowledgment ({}). This API does not enable desktop verification capability advertisement.

requestId is the original status, enroll, delete, or verify RPC's string or integer ID on the same connection, not the server elicitation ID. Use fresh IDs for each operation and a distinct ID for the cancel RPC. Unknown, finished, unrelated, and other-connection requests are no-ops.

The acknowledgment confirms the cancellation signal without waiting for the OS prompt to close. The original RPC completes independently, with cancelled/interrupted when cancellation prevents completion. Cancellation cannot roll back completed effects. It remains effective while a proof waits for outbound queue capacity, but cannot retract a response already enqueued.

Canceling or resolving an elicitation does not itself stop a separate userVerification/verify RPC. Clients must cancel that RPC separately and discard late proofs after the approval is canceled or resolved. Only one native worker runs per app-server; if an OS call remains active after cancellation or timeout, subsequent local operations return failed/providerError until that worker exits.

Thread removal

thread/archive and thread/delete reject attempts to remove a live internal worker with JSON-RPC error -32600. The worker's owner controls its shutdown. For example, a Guardian reviewer remains available to its parent conversation after a client tries to archive or delete it.

After the owner releases the worker, its saved conversation can be archived or deleted normally. Ordinary client-controlled threads keep their existing behavior.

Amazon Bedrock authentication

If model_providers.amazon-bedrock.aws.credential_export is configured, Bedrock setup and Bedrock login return an error without changing configuration or saved credentials. Remove the exporter configuration before selecting another credential source. aws.credential_export and aws.profile cannot be configured together.
