Levi Neuwirth 9ab931d6dd T M4.5: default Python LSP (basedpyright) + LSP-independent filetypes
First real language on the now-correct async + UTF-16 substrate.

- pmacs.lsp.config.python → `basedpyright-langserver --stdio`.
  basedpyright (MIT fork of pyright) re-enables inlay hints /
  semantic tokens in the OSS server that upstream pyright withholds
  for Pylance — matches the deferred-feature roadmap. No init_options:
  strictness is project config (pyrightconfig.json / [tool.pyright]);
  pmacs does not yet advertise workspace/configuration, so an
  editor-side typeCheckingMode would not be honoured regardless
  (documented in-line, with the upstream-pyright one-field override).

- LSP language detection separated from tree-sitter. pmacs.parse's
  extension registry is grammar-gated (rejects "python" — no bundled
  grammar). New user-extensible pmacs.lsp.filetypes map (py/pyi →
  python); active_buffer_language() tries grammar-backed parse first
  (rust/.rs etc. unchanged) then falls back to the map, so a language
  with a server but no grammar still auto-attaches.

- PATH-gated acceptance test mirroring m4_5_rust_analyzer_initializes;
  unique assertion: a real basedpyright must negotiate a
  positionEncoding pmacs can encode — validates Option B against a
  real strict server, not just the fake. Skips when absent.

Gate: fmt clean; clippy --all-targets -D warnings clean; lib
1229/0; m4_acceptance 61/0; m9_1 18/0; m8_1/m8_9/m8_10 green.
