Add a debugging feature to capture all JSON-RPC 2.0 traffic between the
Nori client and ACP agents using the sacp-tee proxy from symposium-acp.
When enabled via --acp-trace CLI flag or acp.trace_enabled in config.toml,
the agent subprocess command is wrapped with:
sacp-tee --log-file <path> -- <original-command> <args>
Key changes:
- Add AcpTraceConfig struct and build_agent_command() in connection.rs
- Add trace_config field to AcpBackendConfig in backend.rs
- Add acp_trace_enabled field to Config, AcpConfigToml, ConfigOverrides
- Add --acp-trace CLI flag to TUI
- Generate session-specific log files: {codex_home}/log/acp-trace-{ts}-{pid}.log
- Add 8 tests covering config, CLI override, and command wrapping
- Update docs.md files for acp, core, and tui modules
Config priority: CLI override > TOML config > default (false)

Resolved conflicts by preserving both feature sets: - ACP traffic tracing (current branch via sacp-tee proxy) - Message history persistence (dev branch) Changes: - Added both trace_config and nori_home/history_persistence fields to AcpBackendConfig - Added both acp_trace_enabled and history_persistence to config types - Preserved enhanced error handling from dev in connection spawning - Added environment variable support (.envs) to subprocess spawning - Merged documentation for both features in tui/docs.md Both features are independent and now work together: - Trace config enables debugging of ACP JSON-RPC traffic - History persistence enables message history storage and navigation 🤖 Generated with [Nori](https://nori.ai) Co-Authored-By: Nori <contact@tilework.tech>

Make ACP traffic tracing available only in debug builds to prevent accidental exposure of traffic logs in production while maintaining zero runtime overhead. Implementation uses a boundary-only approach with conditional compilation guards at exactly two points: - CLI flag visibility (--acp-trace only exists in debug builds) - Command spawn (build_agent_command ignores trace config in release) Config fields flow through all intermediate code unchanged, keeping the implementation simple while ensuring security. 🤖 Generated with [Nori](https://nori.ai) Co-Authored-By: Nori <contact@tilework.tech>
