/**
|
|
* Error types for the AI provider layer.
|
|
*
|
|
* Errors are classified so callers can react appropriately: auth failures are
|
|
* terminal (the key is wrong), rate-limit/overloaded errors are retryable, and
|
|
* budget violations are a client-side guard.
|
|
*
|
|
* See CHUNK#8.md §3.
