chore: remove deploy-main workflow

[mabry1985]

Production deploy is no longer driven by GitHub Actions — handled out-of-band. The workflow's required runner label (`protolabs`, exclusive to `protolabs-main`) has been offline, so every main push was producing a stuck/queued job.

What's removed

• `.github/workflows/deploy-main.yml`
• Updated `docs/internal/dev/system-architecture.md` Release Flow section to drop the `3. deploy-main.yml fires` step

Follow-up

A separate PR will pull the remaining `ubuntu-latest` and `self-hosted` workflows onto the `namespace-profile-protolabs-linux` runner so we stop consuming GitHub Actions minutes.

📝 Walkthrough

Walkthrough

The PR removes the deploy-main GitHub Actions workflow and updates the CI/CD Release Flow documentation. Version sourcing is changed to libs/types/package.json, and the post-release deployment description is updated to reflect an out-of-band model with workflows chained from release tags instead of automatic deployment on main branch pushes.

Changes

Deployment Model Update

Layer / File(s)	Summary
CI/CD documentation update docs/internal/dev/system-architecture.md	Release flow now sources version from libs/types/package.json, removes deploy-main.yml workflow description, and documents production deployment as out-of-band with workflows chained from release tags.

🐰 A workflow once ran with devoted care,
Deploy-main would always be there.
But now it's retired, the docs reflect new ways,
Out-of-band deploys greet the main branch these days. ✨
