better_effect_flutter 0.4.0

Published on pub.dev: https://pub.dev/packages/better_effect_flutter/versions/0.4.0

• Added the repository-level normative semantic contract and an independent
  cross-package conformance suite for Command authority, one-shot delivery, and
  Flutter Runtime ownership alongside the core lifecycle rules.

• Semantic compatibility changes now require the matching conformance scenario,
  affected package changelog entries, and a semantic migration ledger entry.

• Added BetterEffectFeatureScope for feature-owned child Runtimes with
  loading/error/retry startup, nested feature environments, and generation-safe
  restart behavior.

• ViewModels and Commands inside a feature automatically bind to the child
  environment, while feature disposal never closes the parent Runtime.

• Added EffectCommandSelector with strongly typed state and snapshot selection.

• Added default == and custom equality strategies for selected values.

• Added EffectCommandBuilder.buildWhen and matching Consumer support.

• Added read-only EffectCommandSnapshot updates for pending, queued, and trigger-pending counts without artificial state revisions.

• Added immutable CommandPolicy.drop, latest, and queue
  coordination without adding new Command classes.

• Added optional cooperative previous-execution interruption for
  CommandPolicy.latest(cancelPrevious: true).

• Added typed-input debounce and throttle triggers driven by the
  contextual EffectClock service.

• Added bounded FIFO queues with explicit reject-newest,
  drop-newest, and drop-oldest overflow decisions.

• Policy replacement and rejection use ExitInterrupted instead
  of inventing domain failures or a new Exit variant.

• Added EffectCommandPolicyEvent, shared/local policy observers,
  EffectCommandPolicyProbe, and deterministic ManualEffectClock
  regression coverage.

• Existing EffectCommandConcurrency call sites remain source
  compatible and translate exactly to the corresponding policies.
