Two small UX polishes:
1. Switching between chats no longer slams you to the bottom. Each
conversation's scroll position (pixel offset + stickToBottom flag)
is remembered in a module-scoped Map for the lifetime of the
renderer process. Discord-style: leave Chat A scrolled up, peek at
another conversation, come back — same spot you were reading.
Chats left at the bottom keep auto-following new messages on return.
Reload resets everything (session-only, no localStorage).
The restore runs once messages.length > 0 to avoid the browser
clamping scrollTop to a near-zero scrollHeight before the message
list has rendered. A small isRestoringRef guard prevents the
programmatic scroll event from immediately overwriting the saved
position with a clamped value.
2. Changelog page now shows a version badge in the header that compares
the installed app version against entries[0].version from the
server-side changelog feed. Three states:
* `vX.Y.Z · aktuell` (emerald) — installed matches latest
* `vX.Y.Z · Update verfügbar` + `neueste: vA.B.C` (amber) — outdated
* `vX.Y.Z` neutral — installed is ahead of the published feed
(dev/test builds)
Semver compare is integer-major.minor.patch with a graceful
garbage-fallback so a malformed version string doesn't false-flag
a current install as outdated.
