fix: Use commit SHA as version for development builds instead of 'latest'

**Problem**:
- version.json showed "version": "latest" for dev builds
- Non-descriptive and not useful for version tracking

**Solution**:
- Use "dev-{commit_sha}" format for development builds
- Stable releases: "3.4.1" (from tag)
- Development builds: "dev-4ec1a17" (from commit SHA)
- API failure fallback: "dev-unknown"

**Version Format Examples**:
```json
// Stable release
{"version": "3.4.1", "commit_sha": "4ec1a17"}

// Development build
{"version": "dev-4ec1a17", "commit_sha": "4ec1a17"}
```

**Benefits**:
- Clear distinction between stable and dev versions
- version field always contains meaningful information
- No more "latest" placeholder values
