feat: migrate from pre-commit to prek

Replace pre-commit with prek, a faster Rust-based alternative that is
7x faster for installation and 6x faster for execution while being
fully compatible with .pre-commit-config.yaml.

Changes:
- Remove pre-commit from pyproject.toml dev dependencies
- Update scripts/setup-git-hooks.sh to use prek
- Update developer documentation (introduction.mdx)
- Update security documentation (software-security.mdx)
- Update AGENTS.md files with new commands
- Regenerate poetry.lock

prek is installed as a standalone tool via:
- pipx install prek (recommended)
- brew install prek
- uv tool install prek

Benchmarks on Prowler codebase:
- Cold install: 25.18s → 3.42s (7.37x faster)
- Warm execution: 87.53s → 14.80s (5.92x faster)
- Cache size: 170MB → 154MB (9.4% smaller)
