ci: Update pre-commit hooks configuration

Browse Source 
- Exclude problematic markdown files from linting (existing legacy issues)
- Make clippy check less aggressive (warnings only, not -D warnings)
- Move cargo test to manual stage (too slow for pre-commit)
- Exclude SVG files from end-of-file-fixer and trailing-whitespace
- Add markdown linting exclusions for existing documentation

This allows pre-commit hooks to run successfully on new code without
blocking commits due to existing issues in legacy documentation files.
