Replace platform-specific npm package resolution with the meta-package oh-my-opencode and OH_MY_OPENCODE_FORCE_BASELINE=1 env export. The meta-package's JS wrapper handles baseline binary selection, avoiding npm exec binary-not-found errors with platform-specific packages while still supporting non-AVX2 hosts. Also works around the OMO_PACKAGE env var leakage issue by making resolver always output the meta-package name.

Run oh-my-opencode through npm exec instead of bunx so non-AVX2 hosts can install the baseline package without Bun crashing before the package entrypoint runs. Keep the existing package resolver in place so doctor, smoke, and auto-install all follow the same compatibility path.
Make the workstation image select architecture-appropriate oh-my-opencode packages and stop assuming AVX2-capable amd64 hosts. Also upgrade Bun and make the bundled Go download respect the target container architecture so the image builds and installs more reliably across supported platforms.
