v0.4.0

First release under io.github.nowjordanhappy:sketch-kmp. Versions up to 0.3.0 are
upstream's Android-only releases; 0.4.0 is the Compose Multiplatform port of that code.

Added

• Kotlin Multiplatform targets: Android, Desktop (JVM), iosX64, iosArm64, iosSimulatorArm64
• TextField gains an errorMessage: String parameter (default "Invalid input"), so the
  accessibility error announcement stays localisable

Changed

• Published as io.github.nowjordanhappy:sketch-kmp — Maven Central verifies namespace
  ownership, so a fork cannot publish under com.mitteloupe.sketch
• Package renamed to io.github.nowjordanhappy.sketchkmp, sources moved to commonMain
• Depends on the org.jetbrains.compose artifacts instead of the androidx Compose BOM
• SketchRectangleShape, SketchCapsuleShape and SketchCircleShape are now data classes — they previously inherited identity equality,
  making Compose miss its Outline cache and regenerate the sketched path every recomposition
  (Modifier.hachure allocates one inline by default, so this sat on a hot path)

Fixed

• RangeSlider's end thumb was wired to the start thumb's MutableInteractionSource, so
  pressing the end thumb showed no ripple and pressing the start thumb animated both. The
  bug is present upstream too.
• java.lang.Math replaced with kotlin.math in PathSketcher, HachureModifier and
  ProgressIndicator — it does not resolve in commonMain on any target

Removed

• SketchUnderlineShape and SketchVerticalLineShape. A Compose Shape describes an area,
  but these described a zero-area line, so every standard consumer mishandled them —
  background drew an invisible wisp, border flattened the wobble, and Surface clipped
  its content away entirely. They were referenced nowhere, including upstream.
  HorizontalDivider and VerticalDivider already draw these lines correctly.
• TextField's internal Strings value class and its androidx.compose.ui.R lookup, which has
  no Compose Multiplatform equivalent
• The private PreviewRangeSlider and its androidx.compose.ui.tooling.preview import
• Empty consumer-rules.pro / proguard-rules.pro and the library AndroidManifest.xml
