fix(llm): honor a carried failure snapshot on any Error

Browse Source 
markLlmAdapterFailure gated the own-`failure` data property on instanceof
HarnessError, which drops the validated facts exactly when class identity is
lost — two copies of this package in one process (e.g. a source-plane replay
harness throwing into a lib-plane boot) make the replay-thrown LlmError's
SERVER/AUTH code arrive as UNKNOWN and defeat llm-retry's retryable-code
match. The snapshot is already validated field-by-field and cross-checked
against the error's own code, so honor it on any Error.
