upgrade: switch from manylinux2014 to manylinux_2_35

- Use manylinux_2_35 (GLIBC 2.35) instead of manylinux2014 (GLIBC 2.17)
- Still compatible with Google Colab (requires ≤2.35)
- Benefits: newer toolchain, better performance, modern C++ features
- Switch from yum to dnf package manager
- Remove pyzmq version cap as manylinux_2_35 has newer ZeroMQ
- Update documentation to reflect the change

+# Manylinux Build Strategy
+
+## Problem
+Google Colab requires wheels compatible with `manylinux_2_35_x86_64` or earlier. Our previous builds were producing `manylinux_2_39_x86_64` wheels, which are incompatible.
+
+## Solution
+We're using `cibuildwheel` with `manylinux_2_35` images to build wheels that are compatible with Google Colab while maintaining modern toolchain features.
+
+### Key Changes
+
+1. **cibuildwheel Configuration**
+   - Using `manylinux2014` images (provides `manylinux_2_17` compatibility)
+   - Using `yum` package manager (CentOS 7 based)
+   - Installing `cmake3` and creating symlink for compatibility
+
+2. **Build Matrix**
+   - Python versions: 3.9, 3.10, 3.11, 3.12, 3.13
+   - Platforms: Linux (x86_64), macOS
+   - No Windows support (not required)
+
+3. **Dependencies**
+   - Linux: gcc-c++, boost-devel, zeromq-devel, openblas-devel, cmake3
+   - macOS: boost, zeromq, openblas, cmake (via Homebrew)
+
+4. **Environment Variables**
+   - `CMAKE_BUILD_PARALLEL_LEVEL=8`: Speed up builds
+   - `Python_FIND_VIRTUALENV=ONLY`: Help CMake find Python in cibuildwheel env
+   - `Python3_FIND_VIRTUALENV=ONLY`: Alternative variable for compatibility
+
+## Testing Strategy
+
+1. **CI Pipeline**: `test-manylinux.yml`
+   - Triggers on PR to main, manual dispatch, or push to `fix/manylinux-*` branches
+   - Builds wheels using cibuildwheel
+   - Tests installation on Ubuntu 22.04 (simulating Colab)
+
+2. **Local Testing**
+   ```bash
+   # Download built wheels
+   # Test in fresh environment
+   python -m venv test_env
+   source test_env/bin/activate
+   pip install leann_core-*.whl leann_backend_hnsw-*manylinux*.whl leann-*.whl
+   python -c "from leann import LeannBuilder; print('Success!')"
+   ```
