Overview
Adds the desktop 1.0.40 release notes at packages/changelog/content/1.0.40.md (dated 2026-06-06), documenting user-facing changes for the next stable desktop release.

Meetings — join actions in the session header, clearer floating status errors, no post-meeting finalizing accessory message, destructive “Stop meeting” styling, and compact upcoming notifications.

Past notes — related-meeting filtering, up to three key facts in the timeline, and per-summary regeneration.

Notes — more reliable link opening from the desktop app.
