MarkView 1.0.5 — AI-Native Markdown Reader

First release with native rendering for every chart format modern LLMs
actually produce — drop a Markdown file in and it renders the way it was
written.

What's new

• Mermaid diagrams (v11). Flowchart, sequence, state, class, ERD,
  gantt, pie, mindmap, timeline, journey — every type code-splits and
  loads on demand.
• Vega-Lite charts (v5). Bar, line, scatter, heatmap, candlestick,
  stacked area. Anything an LLM can emit as a JSON spec renders as SVG.
• KaTeX math (already in 1.0.3, now verified end-to-end). Inline,
  block, matrices, integrals, Fourier transforms.
• GitHub-flavored Markdown — tables, task lists, footnotes,
  strikethrough.
• Syntax highlighting for 100+ languages via highlight.js.
• Linux default-handler binding — one click in the About panel runs
  xdg-mime default ... text/markdown; the packaged .desktop file is
  already wired up so double-clicking a .md file from any file manager
  opens MarkView.
• Recent Files (already in 1.0.3) on the welcome screen.

Performance

• Cold start < 200 ms on SSD.
• CSS contain: layout style paint on every chart wrapper — scrolling a
  chart-heavy document no longer pegs a core. See the Rendering chapter
  in demo.md.
• Vite production build code-splits Mermaid diagram types into separate
  chunks so a flowchart-only document doesn't pay for gantt/class/ERD
  bundles.

Fixes (internal — carried forward from 1.0.3 line)

• Release builds were loading the dev URL. The Tauri scaffold's
  [features] default = ["custom-protocol"] was missing from
  src-tauri/Cargo.toml, so every release binary since 1.0.0 tried to
  connect to http://localhost:1420 instead of the bundled assets and
  displayed a raw "Connection refused" page. 1.0.5 is the first Linux
  build that actually loads bundled content on first launch.
• Cold-launch chart render race. Opening a file via double-click from
  a file manager (as opposed to clicking from Recent Files) raced the
  async mermaid/vega module load against theme-store initialisation, so
  charts occasionally stayed unrendered. The render effect now uses a
  cancellation predicate checked between every await and a
  data-*-claimed attribute so two overlapping passes can't both render
  the same block.
