Add implementation-ready plans for the in-flight features that lacked
one, and two new provider/protocol items:
- MiniMax provider (cloud arm + Token Plan billing decision)
- Agent Client Protocol (ACP) — dual role: gnoma as ACP agent and as
ACP client driving external agents as router arms
- Network egress allowlist (Learn/Review/Enforce); note the per-session
audit log is already implemented, remaining gap is a viewer command
- Cross-platform (Windows/macOS) code touch-points + build-tag pattern
- Distribution follow-ups (cosign, brew tap, installer, dockers_v2)
Link each plan from its TODO.md entry; mark audit-log item done.
