feat(theseus/screenshot): 0.5.0 — sidebar-first editor, direct save/copy, sounds

Browse source 
Two problems the old editor kept hitting:
- __pending drain race: opening the editor a second time (refresh, back-and-
  forth navigation) found the storage entry already consumed and bailed to
  a blank canvas silently.
- Cross-origin img loading: editor.html at file:///…/addons/screenshot/
  loading a scratch PNG at file:///…/addons-data/ counts as cross-origin
  under Chromium's file-URL policy; setting crossOrigin="anonymous" made
  the load fail outright.

Rebuilt editor v2:
- Load path is idempotent: silentmode.invoke("getBytes", {name}) → addon
  reads the scratch file and returns a data URL. No __pending drain, no
  cross-origin trickery — data: URLs are same-origin and never taint the
  canvas, so getImageData / toBlob keep working.
- Two-canvas model (#base + #over, over is pointer-events:none) so live
  previews don't cost a full re-composite per mousemove.
- Tools: cursor, arrow, rect, ellipse, pen, text. 6 swatches, 3 widths,
  undo / redo (25-deep). Copy + Save at the top bar. Back and Maximize
  buttons in the same top bar so navigation controls stay reachable when
  the toolbar wraps at narrow widths.
- Keyboard: A/R/O/P/T select tool, Esc = cursor, Ctrl+Z/Shift+Z undo/redo,
  Ctrl+S save, Ctrl+C copy.
- Toast surface for save/copy/error feedback.

Sidebar panel gains a direct raw-save path so the user can copy or save the
capture without entering the editor:
- Two-row actions: [Copy] [Save] on top, [Discard] [Edit] below.
- Copy uses navigator.clipboard.write(ClipboardItem); Save uses
  <a download> with a Blob URL — same path Chromium's will-download
  tracker already handles, so the file lands in Downloads and the chip
  updates like any other save.

Inline "clear all" confirmation replaces the native confirm() — the old
system-modal opened over the tab area (out of the sidebar's visual
context) and looked like Windows 95. Now a compact red strip appears
under the Recent header with Cancel / Delete buttons.

Sounds + a sound-on/off toggle in both surfaces:
- Web Audio oscillator-synthesized (no .wav shipped): shutter click on
  capture, two-tone bloop on copy, descending pair on discard/back,
  ascending triad on save.
- Preference stored in silentmode.storage under "soundOn" (default on),
  shared between the panel and the editor.

Simplifications:
- Dropped the addon's "arm" onMessage handler (superseded by getBytes).
- Manifest capabilities: sidebar-panel + capture-tab (no open-tab,
  no toolbar-menu).

Bundled but not shipped — parent session handles the OTA sign + push.

// Screenshot editor. Three stacked canvases: // Screenshot editor v2. Lives inside the sidebar view; no separate tab.
// #committed — pristine bitmap after every applied edit
// #draw — receives pointer events; hosts the live preview during a drag
// #overlay — the crop/blur selection chrome (dashed rect, dim mask)
// //
// Undo/redo is snapshot-based for correctness over cleverness: each committed // Load path (idempotent — this is the key change from v1's __pending drain):
// edit pushes an ImageData onto an undo stack. Redo stack is cleared as soon // editor.html?name=<scratchfile.png>
// as a new edit lands. Memory footprint is width * height * 4 * (stack depth); // → silentmode.invoke("getBytes", {name})
// for a 1920x1080 image at depth 20 that's ~170 MB, so we cap the stack. // → addon reads scratch/<name>.png from disk and returns
// { name, dataUrl:"data:image/png;base64,…", bytes, at, mode }
const UNDO_MAX = 25; // → we set an <img> src to that data URL and draw it onto #base
//
// Two canvases: #base holds the committed image; #over is a preview layer
// that hosts the live drag preview for each drawing tool. On mouseup the
// tool commits its result by drawing #over onto #base, clearing #over,
// and pushing a fresh ImageData snapshot onto the undo stack.
