fix(search): drop the open article when the query is cleared

Measure-pass defect in compose ui 1.12.0: layoutChildrenBlock clobbered
the isPlacingForAlignment flag of child nodes during alignment
placement, so sheet anchors were recalculated from a stale content size.

compose ui 1.12.1 preserves and restores child placement flags, so the
anchor is computed from a consistent content size on the first frame.

+## Architecture
+
+ReSearch is an Android app written in Kotlin and Jetpack Compose.
+
+```text
+com.example.research/
+├── common/   # shared progress, UI, file, archive, notification utilities
+├── core/     # domain models, source validation, operation results
+├── data/     # DictZip, DSL parsing, indexing, paging, repositories
+├── feature/  # search, dictionary download, local import workflows
+└── ui/       # Compose screens, article view, settings, navigation
+```
+
+State is exposed through Kotlin Flow and collected by Compose screens. Long-running work uses coroutines and foreground services where Android requires visible progress.

 ## Dictionary Pipeline
 
 ReSearch supports both downloaded and locally imported dictionaries.
