Anvil v1.0.0 -- Arduino build tool with HAL and test scaffolding

Single-binary CLI that scaffolds testable Arduino projects, compiles,
uploads, and monitors serial output. Templates embed a hardware
abstraction layer, Google Mock infrastructure, and CMake-based host
tests so application logic can be verified without hardware.

Commands: new, doctor, setup, devices, build, upload, monitor
39 Rust tests (21 unit, 18 integration)
Cross-platform: Linux and Windows
