Manually reconstructing the required MSYS environment and prerequisite sequence consumed far more time than compiling the runtime. Codify that knowledge so prepared source trees can be rebuilt incrementally while preserving existing build trees and complete logs. Document this workflow in `AGENTS.md`, including why `--cleanbuild` is unsafe when `src` contains retained working source: it deletes the entire directory.

This provides a repeatable, incremental path for testing
msys2-runtimechanges locally without risking retained worktrees through--cleanbuild.The helper rebuilt
new-msys-2.0.dlllocally, and the next run reused the cached configuration. Hosted CI will skip the package build because noPKGBUILDchanged.
