Subject: [PATCH] fix: optimize Docker builds and update runtime dependencies
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Update axios to 1.7.2 and zod to 3.23.8 for better stability
- Add fast AMD64-only workflow for testing (docker-build-fast.yml)
- Fix multi-platform build issues with better-sqlite3 native compilation

The multi-platform builds were hanging due to better-sqlite3 requiring
native compilation for each platform. This provides a workaround.
