Research direction

Locate the EPUB, AZW3/MOBI, and PDF tag readers and inspect their catch (Exception) handling; the issue does not name their files or tests. Start by tracing how those readers wrap failures as TagExtractionException, then check the existing tests for cancellation and out-of-memory behavior. Done means those conditions propagate while other extraction failures retain the reported unreadable-file behavior.

Description

bug

Problem

The EPUB, AZW3/MOBI and PDF tag readers wrap their work in catch (Exception) and rethrow as TagExtractionException, which also swallows cancellation and out-of-memory conditions and reports them as an unreadable file (the import is then rejected). Cancellation and OutOfMemoryException should propagate. Found while reviewing #212.
