Rebase pre-commit autoupdate onto next branch

[Copilot]

Description of work:

Rebased the pre-commit autoupdate PR onto the next branch to incorporate latest upstream changes while preserving the ruff version update (v0.14.14 → v0.15.0).

Changes incorporated from next branch:

• Workflow updates in test_and_deploy.yml and update-lockfile.yml
• Dependency updates (pixi.lock, pyproject.toml)
• Improved file summing logic in instrument.py and data_manager.py to properly merge cross-sections instead of concatenating
• Enhanced quicknxs_io.py with better file handling
• Additional unit test coverage for instrument.py and quicknxs_io.py

Check all that apply:

• updated documentation and checked that it looks correct in the pull request preview
• Source added/refactored
• Added unit tests
• Added integration tests
