Switch build backend from hatchling to uv_build

[Copilot]

Changes

Updated the build system configuration in pyproject.toml to use uv_build as the build backend instead of hatchling. This change aligns the build system with the project's use of uv for dependency management and provides a more integrated development experience.

Details

The modification updates the [build-system] section:

• requires = ["hatchling"] → requires = ["uv_build"]
• build-backend = "hatchling.build" → build-backend = "uv_build"

Benefits

• Consistency: The project already uses uv for dependency management (uv sync, uv run), so using uv_build for building creates a unified toolchain
• Simplicity: Reduces the number of external dependencies needed for the build process
• Integration: uv build works seamlessly with the uv_build backend

Testing

All existing functionality has been verified:

• ✅ Package builds successfully with uv build
• ✅ Generated wheel and source distribution contain correct files
• ✅ All tests pass
• ✅ Entry points (e.g., train command) work correctly
• ✅ No security vulnerabilities introduced

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• astral.sh
  • Triggering command: curl -LsSf REDACTED (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

On pyproject.toml, use uv build instead of hatchling
