Arc’s Capture, live extension icons and Shift + wheel spaces

Capture this page, in the Site Control Center or with ⇧⌘2, now puts the page on the clipboard with the screenshot sound and says “Screenshot Copied to Clipboard” in Arc’s toast, with a Save button for when you want a file. Chromium draws the image, so it’s never blank, on any display and behind other windows, and Finder no longer opens. Share keeps the control center open under its list, and the lock badge shows the site’s certificate, or “Not Secure”. Reported by Wladimir in #90.

Pinned extension buttons, the Site Control Center and the Extensions menu now follow what an extension sets while it runs: ZeroOmega’s profile ring, AdGuard’s paused shield, and the badge with a count or a warning, drawn the way Arc draws it. Extensions also follow the space’s profile: each profile keeps its own pinned buttons, an extension’s options page opens in a space on the profile that asked for it, and Export Diagnostics names the extension whose proxy is in force. An extension page restored at launch now loads instead of showing an error. Reported by Wladimir in #106 and #107.

Hold Shift and turn a mouse wheel over the sidebar, or tilt the wheel sideways, to move to the next or previous space, with Arc’s timing: one slow notch does nothing, a flick switches. Before your first space the Library slides in. Asked for by Anoninz in #93.

Right-click menus on tabs, favorites, spaces and splits show each item’s shortcut, your own from keybindings.json included, and the reload chevron in developer mode lists Clear Cookies and Refresh and Clear Cache and Refresh, as in Arc. Reported by Wladimir in #89.

Settings ▸ Performance shows what Cra records about its own speed on your Mac: freezes and what came just before them, CPU and memory per process, slow pages and crashed tabs. Nothing leaves the Mac; Help ▸ Export Diagnostics adds it as perf.json when you choose to send a report. Suggested by Wladimir in #91.
