Local Dev 7405e444e7 feat(theseus/screenshot): 0.6.0 — crop + mosaic redaction, right-anchored sidebar controls, real shutter+print sounds
Editor:
- Crop tool restored — drag to select, marquee sits with a dashed acid
  border and a dimmed backdrop for the area you'll discard, then the
  topbar shows Apply crop / Cancel. Applying trims #base to the rect,
  resets undo (dimensions changed), and drops back into the select tool.
  Enter / Esc keyboard shortcuts while a crop is pending.
- Blur / mosaic redaction tool back — drag a rectangle, editor
  downsamples that region of #base to ~12-block granularity and paints
  the blocks back nearest-neighbour. Commits directly (no confirm step).
- Sidebar-window controls (Back, name, Copy, Save, Sound, Maximize)
  reflow: Back + name on the left, Copy + Save + Sound + Maximize on
  the right so the "put the sidebar back to normal size" affordance
  lives where users expect it. Toolbar's drawing tools stay centred.
- Back arrow icon swapped from a chevron to a proper flat arrow
  (line + arrowhead), matching the new browser back/forward glyphs.

Sounds — modeled on Firefox Screenshots' feedback rather than beeps:
- Shutter is now a real photoshoot click: two mirror-slaps built from a
  band-passed noise burst (metallic ping) plus a very short square-wave
  thud each. Sounds like a camera, not a beep.
- Copy is a two-chirp "printer feed" — filtered noise burst on top of a
  sine chirp per beat, staccato ascending pair. Same shape Firefox Easy
  Screenshot uses for "copied to clipboard".
- Save keeps its ascending triad; Discard keeps its descending pair;
  new small ascending pair for Apply crop.

Chrome:
- Browser Back / Forward chevrons (M10 3 L5 8 L10 13 — two segments
  meeting at a point, no shaft) replaced with straight-arrow glyphs
  (line + arrowhead). Reads as a navigation arrow, not an angle bracket.

Bundled but not shipped separately — parent session OTA-signs and pushes.
