v2.4.0 — Formatting Toolbar & Shortcut Search

Write and navigate faster with a one-click Markdown formatting toolbar, searchable keyboard shortcuts, and editor font-size controls. This release also protects vault changes made outside Noteriv from being overwritten.

✍️ Formatting toolbar (#22)

• Markdown notes now have a formatting toolbar below the document title in Live and Source modes. It provides bold, italic, strikethrough, inline code, link, image, quote, code block, task list, table, and horizontal-rule actions.
• The toolbar uses the same commands as keyboard shortcuts, keeps editor focus after an action, and is hidden in View mode, Zen mode, and board notes.

⌨️ Shortcuts (#23, #24)

• Settings → Shortcuts now has a search field. Search command names, categories, action IDs, or key combinations, with a result count and empty-state message.
• Zoom the editor text with Ctrl/Cmd + + or = and Ctrl/Cmd + -, including numpad + and -. The size is limited to 11–24px and saved after adjustment.

🛡️ External changes (#20)

• When a note is changed outside Noteriv, the file on disk is now treated as authoritative. Previously, a stale tab with unsaved in-memory content could write over that external change during reload.

📖 Documentation (#21)

• The repository's docs/ directory is now documented as the canonical source for docs.noteriv.com; the marketing site's /docs route redirects there.

📎 Other

• Bumped the desktop app version to 2.4.0 across package.json, Cargo.toml, tauri.conf.json, and their lockfiles.
