cc-connect kills sessions on single-line stdout >64KB

Issue #189 identifies a concrete reliability bug where cc-connect’s shared agent-read loop in `codexSession`/`claudeSession` uses Go `bufio.Scanner` for stdout parsing, so single-line outputs around/above ~64KB (e.g., JSON/JSONL) trigger `token too long` and terminate the session.

cc-connect kills sessions on single-line stdout >64KB

Issue logs repeatedly show `codexSession: scanner error error="bufio.Scanner: token too long"` and `agent error: read stdout: bufio.Scanner: token too long` right before session interruption, confirming a common read-path crash pattern.
