Home, the round Home button and every app now draw Material Design icons from iconkit instead of lv.SYMBOL. iconkit is a package of the pydevices repository (omnipython-iconkit, PyDevices/pydevices#531), so this repository adds no package for it and lib/ stays the one omnipython-applibs package. Home and appkit import it the same way as before.

Each app's app.json has a new required field, "icon", a Material name from iconkit's 48 px set, replacing "symbol". An app with a tile and no icon, or one iconkit doesn't have, is an error with the app and icon named: when the index is built, and when Home starts. There is no default icon. "tile": false apps need none. The icon docs and contact sheets are on iconkit's side: README and icons page.

appkit's manifest no longer includes iconkit: freeze it beside appkit, as you do pydevices. The appkit tests take iconkit from packages/iconkit/lib in the pydevices checkout (or ICONKIT_LIB), and the index check raises with the fix when iconkit isn't importable. This pull request's CI needs pydevices main to hold packages/iconkit, so it is green only after pydevices#531 merges.

I ran Home on unix MicroPython headless at 800x480 (all four pages) and as a 240x240 and 360x360 round screen, and looked at the frames, before iconkit moved. After the move I ran the appkit index and script tests on CPython against the new location, and confirmed Home and appkit import on unix MicroPython with iconkit taken from the pydevices folder. I did not re-render the Home frames after the move, did not run the appkit MicroPython contract checks (this machine's interpreter has no frozen appkit and they fail the same way without my change), and did not run it on a board. Buttons inside apps still use lv.SYMBOL.

RAM measured on unix MicroPython 1.29 with pygraphics (and its new blit_alpha) built in, running the same binary with iconkit frozen and with iconkit loaded from the filesystem. Heap figures are after gc.collect().

	frozen	from the filesystem
import both sets (24 px and 48 px)	1,824 bytes	152,448 bytes
hold 50 mask() results	5,792 bytes (116 each: the memoryview slice and its tuple)	5,792 bytes
draw 50 icons into a FrameBuffer with iconkit.gfx.draw	512 bytes	1,632 bytes

Frozen, the icon pixels stay in flash: no icon's 576 bytes are ever copied to the heap.
