4.15.5

🐛 Fixes

• Video calls: first Jitsi call after a fresh install or cleared cache now joins directly instead of landing on the pre-join screen. The loading watchdog no longer interrupts slow first-time loads, and its recovery path now preserves the call's authentication token and logs its activity in production. (#3416)
• Video calls: screen sharing in the call window works again on 4.15.x — a build-pipeline gap left a react-dom/client chunk without its module wrapper (ReferenceError: exports is not defined); dependency subpath imports are now externalized and a build-time guard prevents recurrence. (#3417, backport of #3411)
• Screen sharing: picker sources stay stable under the Electron 42 macOS capture stack. (#3417, backport of #3414)
• Sidebar: fixed a crash when formatting shortcut tooltips. (#3417, backport of #3326, fixes #3244)
