fix: enable binary builds for proper GitHub releases and Helm charts

Problem:
- With builds: skip: true, no artifacts were created
- GoReleaser wasn't creating GitHub releases or tags
- Helm chart workflow wasn't triggered (depends on tags)
- No downloadable binaries for users

Solution:
- Enabled builds for both gohoarder and migrate binaries
- CGO_ENABLED=1 for SQLite support
- Added fts5 tag for full-text search
- Builds run natively per platform in split/merge workflow:
  - darwin/arm64 (Apple Silicon Macs)
  - linux/amd64 (x86_64 Linux)
  - linux/arm64 (ARM64 Linux)
- Ignored darwin/amd64 (Intel Macs) to limit build matrix

How it works:
1. Split phase: Each platform builds natively (no cross-compilation)
2. Merge phase: Combines all artifacts, creates release, builds Docker images
3. Docker images still use multi-stage builds (independent of binaries)
4. GitHub release created with tags
5. Helm chart workflow triggered

Benefits:
- Downloadable binaries for all platforms
- Archives created automatically
- GitHub releases with proper tags
- Helm charts published
- Docker images built separately with multi-stage builds
