v0.4.0

Added

• Add an English, skill-local Instagram architecture example showing a
  multi-root Compose app composed from API, repository, user, feed,
  post-detail, comment, and startup-coordinator ViewModels.
• Add nestable, idempotently restorable overrideWith and coroutine-isolated
  runWithOverride APIs to zero- through four-argument ViewModel specs.
• Add the strongly typed Compose selectViewModelState API with an optional
  selector-local equality rule.

Changed

• Make ViewModel.reset() the complete runtime reset: it force-disposes every
  cached generation, including aliveForever, before clearing configuration
  and lifecycle observers.
• Align full-state and selector equality with Flutter: full state uses local,
  global, then reference identity; selected values use local, global, then
  Kotlin ==.
• Freeze each state transition before synchronous listener dispatch so a
  reentrant setState cannot corrupt later listeners' previous/current pair.
• Make Compose watchViewModel and readViewModel re-resolve after their
  handle is recycled instead of retaining the disposed generation.
• Make maybe*Cached return null only for ViewModelError; unrelated
  exceptions now propagate to the caller.

Fixed

• Skip listeners removed before their turn during the current notification.
• Contain failures thrown by the configured error handler so later listeners
  and disposal callbacks still run.
• Preserve explicit null key/tag and false retention values from an active
  legacy or scoped spec proxy instead of falling back to the base spec.
• Guard the complete reset sequence against teardown-triggered nested resets so
  remaining generations still use the outer error and lifecycle pipeline.
• Throw ViewModelError consistently when resolving through a disposed
  binding.
• Keep read-style Compose resolution and typed selectors subscribed only to
  generation changes, avoiding recomposition from unrelated watched
  ViewModels on the same binding.

Tests

• Add serial contract coverage for reset, maybe lookup errors, listener
  mutation, reentrant state, equality fallback, secondary error handling, and
  scoped spec overrides, plus Compose recycle and typed-selector behavior.
