feat: skip workflows on copilot/*, dependabot/*, and pre-commit-ci-update-config branches (#538)

This PR implements branch exclusions for GitHub workflows to avoid
duplicate CI runs on bot-created branches. When bots like Copilot,
Dependabot, or pre-commit-ci create branches and open PRs, the workflows
run twice - once on the push event and once on the pull request event.

## Changes Made

Modified the following workflow files to exclude bot branches from push
events while preserving pull request triggers:

- `test.yml` - Python package testing across multiple Python versions
and platforms
- `machines.yml` - Testing on different machine configurations (Slurm,
PBS, SSH)
- `pyright.yml` - Type checking with pyright
- `test-bohrium.yml` - Bohrium cloud platform testing
- `release.yml` - PyPI release workflow

Each workflow now uses:
```yaml
'on':
  push:
    branches-ignore:
      - 'copilot/**'
      - 'dependabot/**'
      - 'pre-commit-ci-update-config'
  pull_request:
```

## Workflows Intentionally Preserved

- `mirror_gitee.yml` - Preserved to ensure all commits (including from
bot branches) are properly mirrored to Gitee
- `ci-docker.yml` and `publish_conda.yml` - Only run on tags, so already
filtered
- `copilot-setup-steps.yml` - Only runs on specific path changes

## Testing

- ✅ All existing tests pass
- ✅ YAML syntax validated
- ✅ Pre-commit hooks pass
- ✅ Branch pattern matching verified
- ✅ CLI functionality confirmed

This change reduces unnecessary CI resource usage while maintaining full
coverage for legitimate code changes and PRs.

Fixes #537.
