parseSSELine trimmed only leading whitespace before the "data:" check, so
gemini-cli frames prefixed with terminal-redraw escapes (e.g. \x1b[2K\x1b[1A)
failed the check and were silently dropped, stalling the client SSE parser.
Now the SSE parsers and the gemini-to-openai text emit sites sanitize ANSI/
VT100 escapes (preserving \t \n \r) via a ReDoS-safe stripAnsiCodes helper.
