Python LSP via per-project micromamba envs; silence native-comp warnings

- Drop python-mode from the global eglot hook: mode hooks run before
  .dir-locals.el applies, so it would always grab the system pylsp.
  Python eglot now starts per-project from .dir-locals.el pointing at
  the project's micromamba env (interpreter, exec-path, pylsp).
- templates/python-project-dir-locals.el: copy+edit recipe for new
  projects. vkeHF is already wired to env vkehf.
- Suppress (native-compiler) warnings: go-mode and friends reference
  lsp/eglot functions they don't require; harmless noise.

Verified in a GUI session: opening vkeHF/superhet.py connects eglot and
spawns ~/.local/share/mamba/envs/vkehf/bin/pylsp.
