Add tests for important edge cases:
- Nested children (child-in-child): verifies that archives within
archives produce correct multi-level AccessPath chains like
"/archive1.tar.gz:/inner-archive.zip:/deep-file.txt"
- Empty child resolver: no locations leak from empty archives
- Same file path in parent and child: both versions accessible
with distinct FileSystemID routing
- Context cancellation in AllLocations: no hanging

Implement a file.Resolver decorator that composites a parent resolver
with child resolvers created from extracted archive contents. Files from
child resolvers appear transparently alongside parent files.
Key behaviors:
- FilesByPath/FilesByGlob/FilesByMIMEType delegate to parent AND children
- FileContentsByLocation routes to the correct resolver via FileSystemID
- Locations from children get archive-prefixed AccessPath (using ":"
separator matching Java cataloger convention) and unique FileSystemID
- Thread-safe via RWMutex for concurrent access
