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.

+# CI/CD Pipeline Guide
+
+## 🚀 New Simplified Pipeline
+
+### For Releases (Recommended)
+Use the **Unified Release** workflow from GitHub Actions tab:
+1. Go to Actions → Unified Release → Run workflow
+2. Enter version number (e.g., 0.1.25) or choose release type
+3. Click "Run workflow"
+
+This single workflow:
+- ✅ Updates chart version
+- ✅ Creates git tag
+- ✅ Builds and pushes Docker image with proper tags
+- ✅ Publishes Helm chart
+- ✅ Creates GitHub Release with notes
+- ✅ **NO MORE `[skip ci]` NONSENSE!**
+
+### For Quick Fixes
+Use the **Quick Fix Build** workflow when you need to push a fix without ceremony:
+1. Go to Actions → Quick Fix Build → Run workflow
+2. Optionally specify a tag (defaults to 'latest')
+3. Click "Run workflow"
+
+This builds and pushes the Docker image immediately without version bumps.
+
+## Workflow Files
+
+| Workflow | Purpose | Trigger | What it does |
+|----------|---------|---------|--------------|
+| `release-unified.yaml` | **Main release workflow** | Manual dispatch | Complete release process |
+| `quick-fix.yaml` | Emergency fixes | Manual dispatch | Just build & push Docker |
+| `build-and-push.yaml` | CI builds | Tags & PRs | Auto-build on tags/PRs |
+| `release.yaml` | GitHub releases | Tag push | Create GitHub release |
+| `helm-publish.yaml` | Helm chart only | Tags | Publish Helm chart |
+
+## Common Tasks
+
+### Release a new version
+```bash
+# Option 1: Use GitHub UI
+# Go to Actions → Unified Release → Run workflow
+
+# Option 2: Use GitHub CLI
+gh workflow run release-unified.yaml -f version=0.1.25 -f release_type=patch
+```
+
+### Push a quick fix
+```bash
+# Use GitHub UI: Actions → Quick Fix Build → Run workflow
+# Or:
+gh workflow run quick-fix.yaml -f tag=hotfix-1
+```
+
+### Check build status
+```bash
+gh run list --workflow=release-unified.yaml
+```
+
