opentrench v0.4.0

• Pick your buy bot: Cove or BasedBot (⚙ → Trading → Buy buttons). Buy buttons on cards and in the drill-down, right-click → Buy on …, and the buy pane all follow the choice. There is one buy pane; it shows whichever bot is picked. BasedBot opens the token via its r_<referral>_b_<mint> deep link (the bot asks the amount); a web-app link is kept as a fallback. Cove keeps its one-click amounts.
• Referral credit on every buy goes to opentrench: Cove links carry the app's affiliate (base62-encoded into the 14-character tail per Cove's deep-link spec) and BasedBot links carry the app's referral. Neither is a setting.
• Search anyone to favorite. ⚙ → Feed → Favorites now has a people search instead of a blind name field: it lists everyone the feed has seen (including people who only chat and have never called), and when you type it also searches your Discord servers and Telegram groups for members who have not posted at all. Each row shows their calls, messages and where, and one click toggles the crown. Typing a name nothing matches still lets you add it verbatim (alextjh).
• Browse a chat's member list. The same picker has a chat dropdown: pick any watched Discord channel or Telegram group and it lists that chat's members, so you can crown someone who has never posted. Members already in the feed show their calls and messages; the rest read "hasn't posted here yet". Telegram hides the member list of large channels, and Discord only knows the members its client has loaded.
• Sound fixes. The 🔕 in the top bar is now a true master mute: column alerts and J7 pings obeyed only their own switches before and kept playing. A column's bell is the only thing that makes it ping: call alerts come only from chat/calls columns with the bell on (the J7 pane's bell was wrongly counted as a call alert, so every new call also played its tone), and J7 starred-account pings and notifications fire only when the J7 column's bell is on. Bot panes no longer show a bell. The top-bar bell now toggles sound no matter what the desktop-notification permission is; before, it only became a mute after notifications were granted, so users who declined them had no way to silence the app.
• Dark form controls. The page never declared color-scheme: dark, so every native control the OS draws — dropdowns and their popups, scrollbars, date pickers — rendered light. Settings dropdowns are now styled like the text fields, with a matching chevron, and the people picker's scrollbar is themed.
• The last column can be resized. It used to fill the row and was given no resize handle, so whichever column sat on the end — the buy pane, most often, since it is appended when you first buy — was stuck at its width. Every column now has a handle, and the leftover width goes to the last column you have not sized yourself.
