Raw Normal View History

feat(theseus/screenshot): 0.3.0 — sidebar-first flow with explicit "open in tab" 0.3.33 still ships blank screenshots because the whole toolbar-menu → auto- open-editor path can't be made race-free: the moment the editor tab opens it becomes the active tab, and a snapshot of the editor's own tab (before its canvas has drawn from storage) is a valid-looking 24 KB all-white PNG. The lastCapturableTabId fallback I added in a279864 catches the second click, but the first click can still land on the addon-owned tab whenever the user re-triggers before setActive has settled. Rebuild the UX so this class of race can't happen at all: - Drop the toolbar-menu capability. Manifest is back to sidebar-panel + capture-tab + open-tab, so the dock icon opens the panel (never the editor directly). No dropdown, no clip-under-tab-view issue, no auto- jump into an addon-owned tab. - Sidebar has the three capture buttons + a preview <img> + a "Open in editor tab" button. The preview is fed a data:image/png URL returned straight from api.captureTab, rendered inside the sidebar's own document — same origin, no file:// cross-directory gotcha, and the user can see immediately whether the shot actually landed. - Editor.html tab opens only on an explicit "Open in editor tab" click. The addon rewrites __pending at that moment (so the editor always sees the just-selected capture even if a prior editor tab drained the entry), then api.openTab("editor.html", {name}). The editor's storage-based load path is unchanged. - Recent captures ring is kept and now exposed as a horizontal thumbnail strip in the sidebar; clicking a tile re-previews that capture and arms "Open in editor tab" for it. Editor page (editor.html/js/css) unchanged — same crop / arrow / rect / ellipse / pen / text / mosaic-redact / undo / redo / copy / save. Bundled but not shipped — leaving version bump + deploy to the parent session.
