Subject: [PATCH] fix(coding-agent): match server_error and internal_error in
 retry regex (#2117)

The _isRetryableError() regex used literal spaces ("server error",
"internal error") but Codex SSE error events use underscores
("server_error").  Change to .? so both space and underscore (and
direct concatenation) are matched, enabling automatic retry on
transient Codex SSE errors.

fixes #2091
