/**

|
* Claude Code auth/config detection helpers (main process).
|
||
|
|
*
|
||
|
|
* Claude SDK launches can authenticate from env (ANTHROPIC_API_KEY / ANTHROPIC_AUTH_TOKEN)
|
||
|
|
* or from credentials stored under CLAUDE_CONFIG_DIR (default ~/.claude). We use
|
||
|
|
* this to turn opaque "-32603 Internal error" failures into an actionable message
|
||
|
|
* when no auth is configured. NOTE: macOS may store credentials in the Keychain
|
||
|
|
* rather than a file, so 'none' is a heuristic — callers must NOT hard-block on it;
|
||
|
|
* only use it to improve the error message after an actual failure.
