Claude a87222c51f refactor: split Compose UI out of commons into a new commonsUI module
`:commons` is on the CLI classpath, yet it declared Compose UI, Coil, Compose
resources, markdown and desktop Compose as dependencies, dragging ~40 MB of
UI/Skiko jars into every `amy` distribution. This moves every
Compose-dependent file into a new KMP module, `:commonsUI`, that
`api`-depends on `:commons`; `:commons` keeps only the Compose runtime
(stability annotations + snapshot state) and lifecycle-viewmodel.

Files keep their `com.vitorpamplona.amethyst.commons.*` packages, so the split
is a build-graph boundary and no consumer import changed. 236 files were
`git mv`'d (composables, icons, robohash, theme, Coil fetchers, the
`@Composable` relay-client entry points, `composeResources`, and the tests
that exercise them). Two headless files needed surgery instead of a move:
`GalleryParser` lost a vestigial foundation `@OptIn`, and the
`LocalPrivacyLockState`/`lockStateFor` CompositionLocal accessor moved out of
`PrivacyLockState` into its own commonsUI file. The feed DAL under `ui/feeds`
and `ui/note/ParentNote`+`ReplyContext` stay in `commons` because ViewModels
depend on them.

`amethyst`, `desktopApp`, `nappletHost` (NappletWebContract serves the shell
from composeResources) and `benchmark` now depend on `:commonsUI`; `cli`,
`geode` and `marmotBench` do not. commons' androidMain gains an explicit
androidx.core KTX dep it previously got transitively through Compose UI.

CI, crowdin, the icon-font tools and the escaping hook point at the new
composeResources location; CLAUDE.md, commons/ARCHITECTURE.md, a new
commonsUI/ARCHITECTURE.md, CONTRIBUTING, BUILDING and the affected skills
document the boundary. A plan doc under commons/plans records the
classification method and follow-ups.

Verified: JVM compiles for commons, commonsUI, cli, desktopApp; Android debug
compiles for nappletHost and amethyst; commons/commonsUI/cli JVM test suites;
both verifyKmpPurity gates; the cli runtime classpath no longer resolves
Compose UI, material3, Skiko or Coil.
