Subject: [PATCH] fix(woodpecker): use simple Dockerfile and reduce build
 complexity

- Replace complex caching with simple Dockerfile

- Remove cargo-chef complexity that was slowing builds

- Add .woodpecker-base.yml for separate base image builds

- Add Dockerfile.simple for faster builds

- Add Dockerfile.ultrafast for when base image exists
