refactor: separate local build and field dist targets

- Separate local binary build (make build) from field bundle dist (make dist)
- make build now uses direct go build for local development only
- make dist handles cross-platform field binaries with checksums and manifests
- Remove LOCAL_BIN_DIR sync logic from field-binaries.sh
- Update edge-local-dev-guide.md to reflect new build workflow
