Analyze this repository and create or update its README.md. The README is primarily for humans. Agent-specific guidance lives in AGENTS.md — do not duplicate it; link to it once.
Priorities, in order (structure the README this way):
- What this is — 2–4 sentences: purpose, product surface (CLI/API/library/ app/infra), runtime model.
- Usage — how to use the software. This is the main help page. First identify the product type(s) from evidence, then adapt:
- CLI tool: commands, flags, examples, exit codes if evident.
