Claude 2e8bf0d45d build: remove unused :ammolite module
The :ammolite module contained no production Kotlin/Java sources (just
a manifest, build.gradle, and proguard stubs) and no module in the
codebase imports com.vitorpamplona.ammolite.*.

Removes:
- ammolite/ directory (5 files)
- :ammolite project include in settings.gradle
- implementation project(':ammolite') from :amethyst
- androidTestImplementation project(':ammolite') from :benchmark
- :ammolite:testDebugUnitTest from CI workflow and pre-push hook
- -keep class com.vitorpamplona.ammolite.** rules from
  :amethyst, :commons, and :desktopApp proguard files
- Stale references in CONTRIBUTING.md, CLAUDE.md, and the
  gradle-expert skill dependency-graph doc

Small build-graph win: one fewer module to configure, compile, lint,
and spotless-check on every build, and one fewer unit-test target in
both CI and the local pre-push hook.

# Pre-fetch VLC + UPX archives into ~/.gradle/vlcSetup before invoking
# Gradle. The vlc-setup plugin (ir.mahozad.vlc-setup 0.1.0) writes its
# downloads to ${gradleUserHomeDir}/vlcSetup/ and sets overwrite(false),
# so an existing file there makes vlcDownload / upxDownload up-to-date
# and Gradle never opens a socket to videolan.org.
#
# Why curl instead of relying on de.undercouch.gradle.tasks.download:
# curl --retry-all-errors with a long --retry-max-time tolerates a
# sustained get.videolan.org outage far better than the plugin's inner
# retry budget (retries(4) + 5min readTimeout in build.gradle.kts),
# which has been hitting SocketTimeoutException on Windows runners.
#
# Cache hit: the file is already on disk, fetch() short-circuits, this
# step takes <1s. Cache miss: curl downloads with aggressive retries,
# populating the cache for the next run.
#
# Versions are pinned to match desktopApp/build.gradle.kts (vlcVersion
# = 3.0.20) and the vlc-setup extension default (upxVersion = 4.2.4).
# NOTE: vlcVersion lags behind upstream VLC because the Linux plugins on
# Maven Central (ir.mahozad:vlc-plugins-linux) are only published for
# 3.0.20 / 3.0.20-2. Bump only after the Maven artifact is republished.
# macOS does not download UPX — UPX cannot compress .dylib files.

# Lint + focused unit tests + benchmark assembly in one Gradle invocation.
# Previously: one invocation for lint, one for `test` (which compiled all
# six amethyst variants × all flavors), one for `assembleBenchmark`
# (re-walking the same task graph). Combining them keeps the daemon hot
# across phases and lets task-level dedup (e.g. compileKotlin) only
# happen once.
#
# `-PdisableAbiSplits=true` produces a single non-split APK per
# (flavor, buildType) instead of 5 (4 ABIs + universal). The CI only
# uploads the universal-equivalent benchmark APK; per-ABI splits were
# being built and discarded, costing ~600MB of stripped_native_libs
# intermediates and several minutes per run.
#
# Test scope: only Debug unit tests for amethyst. The release/benchmark
# variants are compile-equivalent for unit-test purposes; running all six
# adds ~5× the kotlinc work without catching new defects on PRs. Push to
# main still gets the full test matrix via the production-build path.
