Clair 0.4.0

Added

• Markdown preview: Mermaid flowcharts and sequence diagrams render directly in Clair, with zoom and drag-to-pan controls.
• Settings: choose editor and terminal fonts and sizes, toggle editor line numbers, and set the terminal cursor shape and blink.
• Editor: matching brackets are coloured by nesting depth; unmatched brackets are highlighted.
• Source Control: discard a file's staged or unstaged changes from its row or context menu, with confirmation.
• Updates: an available update appears in a popup at the bottom right of the window.
• Crash reports: after a crash, Clair offers a prefilled GitHub issue on the next launch.

Fixed

• Settings: Esc closes the sheet, typing no longer reaches the covered editor, and the closing transition stays visible.
• Editor: JSON and Terraform highlighting now matches the intended Atom One Dark colours.
• Source Control: row buttons remain clickable when the row also opens a diff.
• Approvals: simultaneous clair calls can each receive an approval card without timing out behind another request.
