🆙 Add Python 3.14 Support

[shaneahmed]

This PR introduces Python 3.14 support and refactors the conda environment testing workflow to improve maintainability, reproducibility, and cross-platform compatibility.

---

✨ Key Changes

✅ 1. Python 3.14 Support

• Updated package metadata:
• Extended supported Python versions in documentation:
• Updated installation docs accordingly

---

✅ 2. Single Source of Truth for Dependencies

• Added a new script:
  requirements/generate_conda_env.py
• This script
  • Parses requirements.txt
  • Converts pip dependencies → conda-forge equivalents
  • Generates:

    requirements.conda.generated.yml
    

  • Eliminates the need to maintain multiple conda YAML files

---

✅ 3. Simplified Conda Workflow

• Refactored .github/workflows/conda-env-create.yml:
• Uses generated environment dynamically
• Matrix testing across:
  • OS: Linux, macOS, Windows
  • Python: 3.11, 3.12, 3.13, 3.14
• Ensures cross-platform compatibility (no shell-specific syntax)

---

✅ 4. Removed Redundant Environment Files

Deleted:

• requirements.dev.conda.yml
• requirements.win64.conda.yml
• requirements.win64.dev.conda.yml

➡️ Replaced by automated environment generation

---

✅ 5. Test Stability Improvements (Python 3.14)

• Updated test expectations for changed Python 3.14 error messages
• Replaced multiprocessing with threading in tests to:
• Improve CI stability
• Avoid platform-specific multiprocessing issues
