Codex uses `exec` subcommand for non-interactive mode and `--json` for streaming NDJSON output. Prompt is passed via stdin.
Use bare binary names instead of /usr/local/bin/ paths since these are mock runners that never execute the binary.
Skips gracefully if codex is not installed or not authenticated.
parseStreamLine only handled Claude's format. Now handles:
- Gemini: {"type":"message","role":"assistant","content":"..."}
- Codex: {"type":"item.completed","item":{"type":"agent_message","text":"..."}}
Also adds streaming integration tests for Gemini and Codex,
gated on PATH detection and auth availability.
Unrecognized Gemini/Codex events (init, user messages, reasoning, turn metadata) were leaking through with raw protocol type strings. Now dropped to return only normalized text/result/tool_use events. Also adds TestAgentRunner_CodexKeepsCLAUDECODE for env parity.
