arbor vs gm-exec

arbor: Arbor builds a semantic dependency graph for codebases, enabling deterministic impact analysis, symbol resolution, and git-aware risk gating. It provides a CLI, GUI, and MCP integration to help developers understand and control the consequences of changes before they happen.; gm-exec: gm-exec is a code execution tool for MCP clients and CLI, supporting multiple languages (JS/TS, Python, Go, Rust, C, C++, Deno, Java, bash). It runs on Bun with PM2-managed process isolation and offers background execution with a 15-second timeout limit.
