v0.1.0

First release.

• Opens Markdown, Typst, LaTeX and Mermaid files for reading and shows them as HTML. Typst is compiled inside the app; LaTeX is converted by pandoc, which must be installed. Typst drawings (CeTZ, Fletcher) and LaTeX TikZ pictures appear as figures.
• Redraws when the file, or a file it includes (\input, .bib, #include, images), is saved by any program, and keeps the scroll position and zoom.
• ⌘-click the preview to open that line in your editor; ⌘E opens a split editor with a live preview.
• File sidebar (⌘B) with native tabs, outline (⇧⌘O), command palette (⌘K), find with a match count, recent files, light and dark themes.
• washi command-line tool: opens files and returns at once, reads stdin with -, and gives machine-readable results with --json (format_version 1) and stable exit codes.
• Update notice: once a day Washi asks GitHub for the latest release and, when there is a newer one, shows brew upgrade --cask washi in a small notice in the bottom-right corner. It never updates itself. The check can be turned off.
• Apple Silicon macOS only. The app has an ad-hoc signature and is not notarized.
