- Backend wheels contain Requires-Dist: leann-core==0.2.7
- Without --find-links, uv resolves this from PyPI which has MLX for all Darwin
- With --find-links, uv uses local leann-core with proper platform restrictions
- Root cause: dependency resolution happens at install time, not just build time
- Local test confirms this fixes Intel Mac MLX dependency issues

Add --find-links to backend builds to ensure they use the locally built
leann-core with fixed MLX dependencies instead of downloading from PyPI.
Also bump leann-core version to 0.2.8 to ensure clean dependency resolution.
Install backend wheels first to ensure they're available when core/meta
packages are installed, preventing uv from trying to resolve backend
dependencies from PyPI.
The leann meta package is pure Python and platform-independent, so there's
no reason to restrict it to Ubuntu only. This ensures all platforms use
consistent local builds instead of falling back to PyPI versions.
Fix issue where uv venv was creating virtual environments with a different
Python version than specified in the matrix, causing wheel compatibility
errors. The problem occurred when the system had multiple Python versions
and uv venv defaulted to a different version than intended.
Changes:
- Add --python ${{ matrix.python }} flag to uv venv command
- Ensures virtual environment matches the matrix-specified Python version
- Fixes "The wheel is compatible with CPython 3.X but you're using CPython 3.Y" errors
This ensures wheel installation selects and installs the correctly built
wheels that match the runtime Python version.

Fix issue where multiple Python versions' wheels in the same dist directory
caused installation conflicts during CI testing. The problem occurred when
matrix builds for different Python versions accumulated wheels in shared
directories, and uv pip install would find incompatible wheels.
Changes:
- Add Python version detection using matrix.python variable
- Convert Python version to wheel tag format (e.g., 3.11 -> cp311)
- Use find with version-specific pattern matching to select correct wheels
- Add explicit error handling if no matching wheel is found
This ensures each CI job installs only wheels compatible with its specific
Python version, preventing "A path dependency is incompatible with the
current platform" errors.

- Add lint and format check to GitHub Actions CI pipeline
The build workflow was checking for matrix.os == 'ubuntu-latest',
but we changed the matrix to use 'ubuntu-22.04', causing the
pure Python packages (leann-core and leann) to never be built.
Changed to use pattern matching [[ == ubuntu-* ]] to match any
Ubuntu version.
This explains why v0.1.9 only published the C++ backend packages
but not the pure Python packages.
- Check if version is already updated before trying to update
- Check if tag already exists before creating
- Check if GitHub release already exists before creating
- This allows re-running the workflow after partial failures
Previously, if the workflow failed after updating version but before
completing the release, it couldn't be re-run with the same version.
- Explicitly use ubuntu-22.04 instead of ubuntu-latest
- Add Python 3.13 to the build matrix
- This ensures we build on the same OS version as Google Colab
- Revert to simple Ubuntu 22.04 builds that should work with Colab
- Remove all manylinux container complexity
- Colab runs on Ubuntu 22.04, so direct builds should be compatible
- Restore build-reusable.yml to v0.1.5 version
- Remove cibuildwheel option from release workflow
This should fix the overcomplicated build issues while maintaining
Colab compatibility through direct Ubuntu 22.04 builds.

- Create separate CI workflow for testing cibuildwheel
- Support conditional build workflow selection in release process
- This allows building wheels compatible with Google Colab and older systems
- Maintains backward compatibility with existing build process
- Use cibuildwheel for professional wheel building
- Specifically use manylinux2014 for Google Colab compatibility
- Supports Python 3.9-3.12 on Linux and macOS
- Handles monorepo structure with separate builds per package
- Includes basic import tests for each package
- This should resolve compatibility issues with older systems like Google Colab
- Use actions/checkout@v3 instead of v4 (Node.js 16 vs 20)
- Use actions/setup-python@v4 instead of v5
- Use actions/upload-artifact@v3 and download-artifact@v3
- This fixes GLIBC version errors in manylinux2014 containers
- manylinux2014 (CentOS 7) has glibc 2.17 but Node.js 20 needs 2.25+
- Add manylinux2014 Docker containers for Linux builds
- This will generate wheels compatible with older Linux systems (CentOS 7+, Ubuntu 16.04+)
- Separate build logic for container vs regular environments
- Install appropriate system dependencies for yum-based manylinux environment
- Use pip instead of uv in containers for better compatibility
- Fix Python version format for manylinux container paths
- Remove --plat manylinux2014_x86_64 flag that was causing build failures
- Let auditwheel automatically determine the appropriate manylinux tag
- Add auditwheel show command to display compatibility info

- Fixes compatibility issues for users on Ubuntu 22.04 and similar systems
