Walkthrough

This PR updates GitHub Actions runner OS versions across multiple workflows (macos-14 → macos-15, windows-2022 → windows-2025, ubuntu-latest → ubuntu-slim), restructures the pre-commit configuration with prioritized hook execution and new hook repositories, and relaxes the nanobind dependency version constraint.

Changes

Cohort / File(s)	Summary
GitHub Actions Workflow Updates .github/workflows/cd.yml, .github/workflows/ci.yml, .github/workflows/upstream.yml	Updated CI/CD runner matrices: replaced macos-14 with macos-15 (added macos-15-intel variant), replaced windows-2022 with windows-2025. Adjusted matrix inclusion blocks accordingly.
GitHub Actions Runner Configuration .github/workflows/release-drafter.yml, .github/workflows/templating.yml	Changed runner from ubuntu-latest to ubuntu-slim for respective jobs; no logic or step modifications.
Pre-commit Hook Infrastructure .pre-commit-config.yaml	Comprehensive restructuring: introduced priority-based hook execution (levels 0–3), added new hook repositories (validate-pyproject, check-jsonschema, typos, cmake-format, prettier, ruff, bibtex-tidy, uv-lock), removed multiple legacy hooks, and reorganized sections with descriptive headers.
Build System Configuration pyproject.toml	Relaxed nanobind version constraint from >=2.10.2 to ~=2.10.2 (compatible-release semantics); added PC170 deprecation entry to repo-review ignore list.

Poem

🐰 The runners hop to newer ground,
macOS-15 and Windows-2025 abound!
Pre-commit hooks now dance in line,
With priorities set, so clean and fine.
Nanobind breathes a looser embrace—
Infrastructure blooms at a steady pace! 🌱

In `@pyproject.toml`:
- Around line 312-316: The nanobind version constraint is duplicated between
[build-system].requires and [dependency-groups].build (the "nanobind~=2.10.2"
entry); add a clear inline comment next to the duplicated entry and/or add a
short note to the repository CONTRIBUTING.md explaining that
[build-system].requires and [dependency-groups].build must be kept in sync when
updating nanobind (and similarly linked build deps), and include which
file/section to update to avoid future drift.
