Pre-filter plugin for python-lsp-server that handles trivial changes
instantly (whitespace, comments, docstrings, imports, fast syntax errors)
to reduce full analysis overhead. Mirrors the copy_if pattern from
Semantics.CopyIfTactic for Lean.
Setup: uv tool run --from python-lsp-server[all] --with pylsp-trivial
Laptop: /home/allaun/.local/lib/pylsp-trivial
