feat(import): embed Microsoft MarkItDown for any-file → Markdown import

Browse Source 
- File → Import with MarkItDown (Any Format)…: PDF, DOCX, PPTX, XLSX,
  Outlook .msg/.eml, EPUB, images, CSV/JSON/XML, ZIP (audio/OCR via the
  [all] extras) — verified live against HTML, XLSX (our own exporter's
  output), and PDF fixtures
- Command auto-resolution with caching: markitdown binary → python -m
  markitdown → python3 -m markitdown
- SEC-1 argv discipline (execFile only, user paths never through a shell),
  50MB cap, 120s timeout, sanitized errors that surface markitdown's own
  "pip install 'markitdown[pdf]'" hints for missing format extras
- Output lands next to the source as <name>.md (numeric suffix, never
  overwrites) and opens in a new tab; markitdown:available/convert IPC
  allowlisted for renderer flows
- Help → Dependencies lists MarkItDown; README/UPDATES updated (v4.6.1)

12 new tests (629 green); lint clean; clean app boot
