feat: PDF support + Split View (P1 roadmap items)
#74 — Support PDF complet: - backend/pdf_reader.py — pymupdf/pypdf text extraction - .pdf added to SUPPORTED_EXTENSIONS in indexer.py - PDF-aware file view API endpoint (metadata, text preview) - Streaming endpoint /api/file/{vault}/pdf/stream - Frontend PDF viewer with iframe, toolbar, download - CSS for PDF viewer container #75 — Split View (PaneManager): - New module frontend/js/pane-manager.js — ES module - 1-4 pane CSS grid with resize handles - Split right/down via keyboard (Ctrl+Alt+\) or PaneManager API - Persistence in localStorage (obsigate-panes) - Collapse to single pane, per-pane active state 285 tests passent
