Add GDAL dependencies to CI for Python 3.14 support

[Copilot]

Python 3.14 tests fail across all OS platforms because pyogrio lacks pre-built wheels and requires GDAL to build from source.

Changes:

• Install GDAL system libraries before pip install on all platforms:
  • Ubuntu: apt-get install gdal-bin libgdal-dev
  • macOS: brew install gdal
  • Windows: MSYS2 with dynamic version detection via gdal-config
• Add Python 3.14 to test matrix

Pre-built wheels continue to be used on Python ≤3.13; GDAL installation enables source builds on Python 3.14+.

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:

• esm.ubuntu.com
  • Triggering command: /usr/lib/apt/methods/https (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)
