fix: completely overhaul the CI/CD pipeline to not suck

BREAKING CHANGE: Removed auto-version-bump workflow that was causing [skip ci] hell

New features:
- Unified release workflow that handles everything in one go
- Quick fix workflow for emergency deployments
- No more [skip ci] preventing Docker builds
- No more manual tag juggling
- Single button release process

The old pipeline was a disaster with disconnected workflows, auto-version-bumps
with [skip ci] that prevented Docker builds, and required manual tag deletion/
re-pushing to trigger builds. This new pipeline is actually usable.
