Switch the Ko-Fi support links to https://support.koalastuff.net across the
README badge, the extension footer (popup.html/template.html, label
"Support KoalaSync") and remove the now-unused KOFI_URL constant. Stop
generating/sending the anonymous uninstall token: initUninstallURL() now
registers the feedback URL without the `t` parameter or storage write.
CHANGELOG updated to match.
Also guard the client CMD_ACK path: only ACK a command sender that is still
a known peer in the room, so we don't emit ACKs to peers that already left
(which the server now drops as absent-peer ACKs anyway).

Adds application-level ping/pong between extension and relay server.
Extension sends PING every 15s, server echoes PONG. Round-trip time
displayed in Status tab (green/yellow/red color-coded).
Server also forwards PING with target peerId and routes PONG back,
enabling future peer-to-peer ping without server restart.
Extension already responds to incoming peer PINGs.
See CHANGELOG.md for details.
- Fixed episode guard regex to support Sxx:Exx title format (Jellyfin/Emby)
and any non-alphanumeric separator between season and episode numbers
- Migrated username, roomId, password, serverUrl, useCustomServer from
chrome.storage.sync to chrome.storage.local for per-device isolation,
preventing automatic cross-device room joins with duplicate names
- Added one-time migration from sync to local for existing users
