Bioscratch 0.5.0

Bioscratch 0.5.0

Bioscratch 0.5.0 is a reliability and workflow release for both the native
Tauri app and the VS Code extension. It makes Markdown files open in the right
editor from more places, strengthens multi-window document handling, and adds a
large set of typing, paste, list, and table fixes.

Highlights

Open Markdown consistently in VS Code

• Markdown files now route into Bioscratch when opened from Explorer, chat
  links, other extensions, restored tabs, and other VS Code entry points.
• The bioscratch.setAsDefaultEditor setting remains the user-controlled
  switch for this behavior.
• A temporary plain-text tab created by another command is closed only after
  the Bioscratch editor has opened successfully, avoiding duplicate tabs.

Safer closing for unsaved documents

• Closing a dirty tab or window now offers three explicit choices: Delete,
  Cancel, and Save.
• Delete discards the unsaved document and removes its autosave recovery
  copy; Cancel leaves the tab or window untouched; Save completes the
  save before closing.
• The same flow is used for the active tab, background tabs, keyboard close,
  toolbar close, native-window close, and app quit paths.
• Save cancellation or failure no longer closes the document accidentally.

Open Recent across every window

• Open Recent now has a searchable picker with keyboard navigation.
• Recent-file updates are serialized and written atomically in the Tauri
  backend, preventing concurrent windows from losing entries.
• A recent file opened or saved in any Bioscratch window is broadcast to every
  other window and appears the next time Open Recent is shown.
• Finder/Open With requests are routed to one appropriate window instead of
  opening the same file in every window.

Better Markdown editing

• Added and hardened inline Markdown completion for emphasis, links, inline
  math, horizontal rules, Mermaid fences, and + list markers.
• Markdown punctuation remains literal inside code spans and code blocks.
• Plain-text paste can create useful Markdown structure, while rich HTML keeps
  its structure and surrounding inline marks.
• Pasting inside inline code behaves like typing and cannot create nested
  Markdown formatting.
• Nested lists now indent, outdent, and serialize correctly in both editors.

Stronger table behavior

• Tab and Shift+Tab navigate cells predictably; Tab from the last cell creates
  a new row.
• Table cells support hard line breaks, inline math, links, and formatting
  without corrupting the surrounding GFM table.
• Literal pipes are escaped on export.
• Unsupported block content pasted into a table cell is preserved as literal
  cell text instead of creating invalid nested tables or lists.
• Deleting a selected table now removes the complete table reliably.

Native app polish

• Secondary Tauri windows open wide enough to keep the complete toolbar on one
  row.
• The macOS Quick Look extension build keeps its sandbox entitlement during
  ad-hoc and Developer ID signing.

Validation

• 92 frontend regression tests across Markdown, tables, lists, close flow, and
  multi-window recent-file behavior.
• 6 Rust backend tests.
• Production TypeScript/Vite build for the Tauri frontend.
• Typecheck and production bundle for the VS Code extension.
• Live two-window Tauri verification for recent-file broadcasting.
• Packaged macOS app verification of the native dirty-close flow.
