Add Sphinx documentation for cuda.pathfinder

[Copilot]

This PR implements comprehensive Sphinx documentation for cuda.pathfinder to replace the current README-only documentation approach.

Changes Made

Documentation Infrastructure

• Created complete Sphinx documentation setup in cuda_pathfinder/docs/ following the established CUDA Python documentation patterns
• Configured pathfinder-specific settings including project name, version environment variables, and URL paths
• Set up version management with nv-versions.json containing version 1.1.0 and latest

Documentation Content

• Main documentation includes the full cuda.pathfinder README content rendered as proper Sphinx documentation
• Added comprehensive API reference with detailed documentation for all public APIs:
  • cuda.pathfinder.SUPPORTED_NVIDIA_LIBNAMES constant
  • cuda.pathfinder.load_nvidia_dynamic_lib() function
  • cuda.pathfinder.LoadedDL class
  • cuda.pathfinder.DynamicLibNotFoundError exception
• Added release notes for versions 1.0.0 and 1.1.0 with content from GitHub releases
• Maintained consistent styling and navigation with other CUDA Python component documentation

Integration Updates

• Updated main CUDA Python documentation (cuda_python/docs/source/index.rst) to link to new Sphinx docs instead of raw README
• Updated root README.md to point to the new documentation URL: https://nvidia.github.io/cuda-python/cuda-pathfinder/latest
• Enhanced build_all_docs.sh script to include pathfinder documentation in the complete build process
• Updated CI workflow (build-docs.yml) to handle cuda-pathfinder as both an individual component and part of the "all" components build
• Updated doc preview CI to include cuda-pathfinder documentation links alongside cuda-core and cuda-bindings

Build System

• Pathfinder documentation can now be built independently with ./build_docs.sh or as part of the complete documentation suite
• Configured proper environment variable handling (SPHINX_CUDA_PATHFINDER_VER) for versioned builds
• Set up redirection pages and version switching consistent with other components
• Uses nv-versions.json format for version management (removed legacy versions.json)

Documentation Standards

• Updated contribute.md to follow Apache 2.0 license format consistent with cuda-pathfinder licensing
• Set copyright year to start from 2025
• Removed unnecessary static assets and configuration sections
• Cleaned up intersphinx mappings to include only essential references
• Updated cuda-core and cuda-bindings README files to consistently reference nv-versions.json instead of versions.json

The new documentation provides a professional, searchable interface that matches the existing CUDA Python documentation ecosystem while preserving all the detailed technical content from the original README.

New Documentation URLs:

• Latest: https://nvidia.github.io/cuda-python/cuda-pathfinder/latest/
• Versioned: https://nvidia.github.io/cuda-python/cuda-pathfinder/1.1.0/

Doc Preview URLs now include:

• Main CUDA Python docs
• cuda-core documentation
• cuda-bindings documentation
• cuda-pathfinder documentation (newly added)

Fixes #760.

I've addressed all the review feedback in commit 12c065f:

• Fixed all references from cuda-bindings to cuda-pathfinder and versions.json to nv-versions.json
• Removed unnecessary static image files and support.rst
• Populated API.rst with public APIs from pathfinder README
• Fixed copyright year and cleaned up conf.py
• Updated contribute.md to follow cuda-core format with Apache 2.0 license
• Removed old versions.json file

The documentation should now be consistent with the cuda-core format and ready for review.

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:

• docs.python.org
  • Triggering command: /usr/bin/python3 /home/REDACTED/.local/bin/sphinx-build -b html source build/html/1.1.0 -j 1 -d build/.doctrees (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)

Updated the doc preview CI to include pathfinder documentation link in commit e86e775. The doc preview comments will now show links for cuda-pathfinder alongside cuda-core and cuda-bindings.
