* fix(oauth): classify an embedded invalid_grant in a refresh error body
Cline answers a dead refresh_token with
400 {"data":"","error":"failed to refresh token: invalid_grant","success":false}
The code is the tail of a sentence — neither a bare code nor an
"error":"<code>" field pair — so extractOAuthErrorCode returned null.
A null classification means refreshClineToken emits no unrecoverable
sentinel, so a permanently consumed refresh_token is handled as a
TRANSIENT failure. tokenHealthCheck therefore never reaches its
unrecoverable branch, and never runs the credentialsChangedSinceSweep
race guard, the "please re-authenticate this account" message, or the
dead-token clear for rotating providers. The connection instead stays
active with errorCode "refresh_failed", retries the same consumed token
3x per sweep behind an exponential backoff, and 401s every request
routed to it indefinitely with no actionable operator signal.
Scan for a known unrecoverable code embedded in the error value as a
last resort, after the exact-match and nested-JSON paths, delimited on
both sides so server_error, xinvalid_grant, my_invalid_grant_flag and a
502 HTML page all still classify as null.
Also add cline to ROTATION_LOCK_GROUP: refreshClineToken reads a new
refreshToken out of every response body and a measured refresh rotated a
connection's stored token, so sibling connections must not refresh
concurrently. cline was already listed in tokenHealthCheck's
ROTATING_REFRESH_PROVIDERS but missing from the serializer.
* docs(changelog): add fragment for cline refresh token error classification
