3.3.0

Added

• Edit-mode indicator. A new optional setting (Settings → Journal Folder →
  General → Edit-mode indicator, off by default) draws a thin coloured rule
  down the left edge of the editor so it's obvious at a glance whether a note is
  being edited or read: an accent rule in Live Preview, a muted-grey rule in
  Source mode, and nothing in reading view. It follows your theme's colours,
  adds no layout shift, and applies to every note in the vault.

Changed

• Updated the build toolchain and dependencies (TypeScript 6, Svelte, Vitest,
  esbuild, typescript-eslint, and others). No behavioural change.
