chore: Improve CodeRabbit path filters configuration (#712)

## ℹ️ Description

This PR improves the CodeRabbit configuration to ensure all important
project files are reviewed while excluding only build artifacts and
temporary files.

The previous configuration used a blanket `!**/.*` exclusion that was
unintentionally filtering out the entire `.github` directory, including
workflows, dependabot config, issue templates, and CODEOWNERS files.

## 📋 Changes Summary

- **Added** `.github/**` to include all GitHub automation files
(workflows, dependabot, templates, CODEOWNERS)
- **Added** root config files (`pyproject.toml`, `*.yaml`, `*.yml`,
`**/*.md`)
- **Removed** overly broad `!**/.*` exclusion pattern
- **Added** specific exclusions for Python cache directories
(`.pytest_cache`, `.mypy_cache`, `.ruff_cache`)
- **Added** explicit IDE file exclusions (`.vscode`, `.idea`,
`.DS_Store`)
- **Added** `pdm.lock` exclusion to reduce noise

### ⚙️ Type of Change
- [x] 🐞 Bug fix (non-breaking change which fixes an issue)
- [ ] ✨ New feature (adds new functionality without breaking existing
usage)
- [ ] 💥 Breaking change (changes that might break existing user setups,
scripts, or configurations)

## ✅ Checklist

standards.
- [x] I have tested my changes and ensured that all tests pass (`pdm run
