Feature Request: Add ACP support for Oh-My-Pi (omp.sh) to leverage its high-performance Rust core and Anthropic Max subscriptions and others #3107

The Problem

Currently, Buzz's ACP harness is coded to support only Claude Code, Codex, and Goose. While capable, Claude Code can feel heavy and slow for rapid terminal workflows.

Why support Oh-My-Pi (omp.sh)?

Developers need a lighter, faster alternative. Oh-My-Pi is a terminal-native AI agent that offers two massive advantages:

1. Raw Performance: Built on a native Rust core, tools like ripgrep and bash run in-process (zero fork-exec overhead). It is incredibly fast, uses token-efficient edits, and is much snappier than Claude Code for local development.
2. Multi-Provider Flexibility: omp supports everything (OpenAI, Anthropic, local models). We can seamlessly plug in our preferred models and billing setups (like an Anthropic Max subscription) without being locked in.

The Solution

Please update the Buzz ACP bridge to support omp.sh as a valid agent, or transition to a generic ACP implementation so that high-performance, multi-provider CLIs can plug and play out of the box.
