[ashwinb]

TL;DR

Enhanced pre-commit configuration with additional hooks for improved code quality checks.

What changed?

• Added --assume-in-merge argument to the check-merge-conflict hook
• Added exclusion for Python files in trailing-whitespace hook to avoid duplication with Ruff
• Added several new pre-commit hooks:
  • check-yaml with unsafe flag enabled
  • detect-private-key for security
  • check-executables-have-shebangs
  • check-json for JSON validation
  • check-shebang-scripts-are-executable
  • check-symlinks
  • check-toml for TOML validation
