MainSequence Desktop 0.4.15 preview

Agent icons that are larger than Claude can embed now appear. Claude's native image is
limited to 128 KiB of markup and draws icons at 20–32 px, while Command Center accepts
icons up to 512 KiB and 512 px. Back Office Helper's 512×512 PNG icon (105 KB, poses
91–112 KB) was dropped for that reason. The worker now decodes such PNGs and shrinks them
to at most 128 px, using nearest-pixel scaling for pixel art, so each pose embeds in about
16 KB. Small icons are unchanged; animated icons keep their frames while they fit.

Validation: 89 Node tests, nine native Desktop simulator tests, loader validation and
distribution checks passed. Against the real backend, Back Office Helper's icon was drawn
in the list and details and all five poses fit. Bundles devtools 0.2.8, now published to
npm. The backend constraint is tracked in Main-Sequence-Server-Side/tdag-django#1136.
