Ports 7c91079 onto the split modules — it landed on main in plugin.js, which
this branch deletes.
Every roster click resolved the bot's canonical Bot Chat by name and opened
it as a tab. Nothing records a tab close (this plugin keeps no closed set;
core's tile bucket only forgets), so a Bot Chat the user had closed came back
beside every newer thread on every bot switch. A click is now "go to this
bot": when the bot's workspace already holds tabs, the one the user last had
active is fronted and no chat is resolved or opened. The forever-chat opens
only when the bot has nothing open, or on the explicit ask — a new "Open Bot
Chat" row-menu item.
The claim such a click records carries only the fronted tab, so the reclaim
listener skips it and cannot resurrect the closed chat. focusExistingBotTab
is feature-detected, so an older shell keeps opening the canonical chat.
Dropped from the port: the Bots home "Open chat" button, a surface this
branch removes. The .mjs test is replaced by a real one — its two
source-reading cases become a render of the menu item in bot-row.test.tsx
and, for the reclaim guard, the claim-shape invariant the guard reads.
Stubbing usePluginI18n there also means the row's localized labels render as
text in tests instead of empty.
