Port: Handle invalid book id tags more robustly

[Copilot]

• Update usfm_parser.py: Truncate book code to 3 characters when longer than 3
• Update usfm_text_base.py: In start_book, add early return if verse_ref.book is already set and doesn't match the new code (handle multiple \id markers)
• Update usfm_file_text_corpus.py: In _get_id, add truncation to 3 chars if id has no space or space after position 3; always uppercase the result
• Update test data files: Change 03LEVTes.SFM and 131CHTes.SFM to use full book names (without " - Test")
• Add tests in test_usfm_memory_text.py for invalid/truncated/multiple/no-space book code scenarios
• Move pytest import to the top of test_usfm_memory_text.py
• Use specific RuntimeError (not generic Exception) in the three error-raising test cases

Done in ad16cf1. The ValueError raised in start_book is caught and re-wrapped as RuntimeError by the parser, so all three error-raising tests now assert RuntimeError.
