Make the release pipeline run and publish the missing model asset

[JeremySNR]

Summary

The README's quick start fails at every step for a new user. This PR fixes the parts that live in the repo.

• release.yml: the image job used ${{ }} expressions inside { } flow mappings. That's invalid YAML, so every run failed in 0 s and no Docker image or desktop installers were ever published. They're now block mappings. The installer job also gets contents: write so electron-builder can upload to the draft release.
• models.yml (new, manual trigger): exports SigLIP to ONNX on a GitHub runner with scripts/export_siglip.py, checks parity against PyTorch, and uploads siglip-base-multilingual.tar.bz2 to the models-v1 release that metachlorian models fetch downloads (OPEN_QUESTIONS Q4).
• Dockerfile: OCI labels so the ghcr.io image links to this repo.

After merging

1. Rename the default branch to main so scripts/install.sh's raw URL resolves.
2. Run Publish models from the Actions tab.
3. Tag v0.1.0 to publish the image and draft installers.

Low Risk
Changes are limited to GitHub Actions, Dockerfile metadata, and release asset publishing—no application runtime or auth logic.

Overview
Unblocks release and model publishing that were failing or missing from the repo.

release.yml fixes invalid YAML in the Docker image job (GitHub expressions inside flow-style with blocks), which prevented the workflow from running at all. The desktop build job now grants contents: write so electron-builder can upload installers to a draft release.

Adds a new manual workflow models.yml that exports SigLIP to ONNX via scripts/export_siglip.py, checks parity, packages siglip-base-multilingual.tar.bz2 (+ SHA256), and uploads to the models-v1 release used by metachlorian models fetch.

The Dockerfile gains standard OCI image labels linking ghcr.io images back to the repo.
