chore: bump version to 4.16.0

[jeanfbrito]

Summary

Promotes 4.16.0-alpha.4 to stable 4.16.0.

• Bump package.json version to 4.16.0
• Bump electron-builder.json mac.bundleVersion to 26080 (first macOS build shipped in August 2026)
• Document the bundleVersion bump convention (YYMM + monthly build counter) in AGENTS.md

What ships in 4.16.0

🐛 Fixes

• Render the TopBar correctly on Linux in sidebar and hidden navigation layouts (fix: render TopBar on Linux in sidebar and hidden layouts #3449)

✨ Improvements

• Unify Windows and Linux shell chrome and menu bar: the menu bar is hidden by default on Windows/Linux (press Alt to reveal it temporarily; Settings or Ctrl+Shift+M pins it visible), and Linux now gets the same client-side window chrome as Windows — embedded window controls, no native title bar, softly rounded corners (feat(ui): unify Windows/Linux shell chrome and menu bar #3450)
• Rework the tab bar downloads indicator with a Chrome-style presentation (feat(downloads): Chrome-style downloads indicator in the titlebar #3441, feat(downloads): rework tab bar downloads indicator #3443)

🔧 Internal

• Update translations from Lingohub (Language update from Lingohub 🤖 on 2026-08-10Z #3447)
• Add desktop UI guidelines and a dev-app verification skill for contributors (docs: desktop UI guidelines and dev-app-verify skill #3445)
• Ignore local agent tooling state in git (chore: ignore local agent tooling state #3448)

Test plan

• validate-pr checks green on all 3 platforms
• Tag 4.16.0 after merge, confirm full asset matrix on the release build

Summary by CodeRabbit

• Release
  • Updated the application version to 4.16.0.
  • Increased the macOS release build identifier for App Store and notarized releases.
• Documentation
  • Added guidance for maintaining macOS release build identifiers and tracking their required format.
