simple_query_shared

Shared infrastructure for non-Android simple_query platform backends.

Provides:

• LocalFileSystemFallback — filesystem-based query/mutate/observe for files and media domains, with path traversal protection and async enumeration
• BaseNonAndroidSimpleQueryPlatform — abstract base that wires together a native Pigeon bridge and the filesystem fallback, with try-native-then-fallback routing
• NonAndroidNativeBridge — handles Pigeon method channel communication, platform exception mapping, and observer lifecycle management
• DarwinQueryPlatform — shared iOS/macOS base class with common capabilities, extension handlers, and namespace routing

Platform packages (simple_query_ios, simple_query_macos, simple_query_windows, simple_query_linux) depend on this package. You don't need to depend on it directly.
