Patrick Buckley addb8d0be8 feat(attachments): capability-gated client-side fallback (pdf->text, audio->transcript)
When the active model can't ingest a kind natively, the wire resolver
converts it client-side instead of sending a part the model can't read.
Per-kind ownership, no shared machinery: PDF text-extraction is a
pure-local PDF concern; audio transcription is an STT concern memoized
in the audio domain.

- core/pdf.py: extract_pdf_text via pypdfium2 (pure-local, no network, no
  cache — re-run per build; page-capped)
- core/audio.py: transcribe_cached — non-raising, memoized by
  (alias, content-hash); backend failures not cached
- session._wire_content_part: per-kind dispatch — native where the model
  supports the kind (supports_pdf / supports_audio_input), else fallback;
  display/export resolve natively so no conversion fires on a render
- image left ungated (pre-existing behavior unchanged)
- pyproject: pypdfium2 dependency + mypy untyped-import override
- tests: pdf extraction, transcript memoization, per-kind gate dispatch
