Kevin Bortis 5e00a01e21 Add FLAC error handling regression tests ...

Regression tests for the error handling improvements in
fix/flac-error-handling (PR #23). The fix changed decode/encode to
return 0 instead of (size_t)-1 on failure, added NULL allocation
checks, and fixed a decoder memory leak on init failure.

Tests added (flacErrors suite):
- decode_garbage_returns_zero: random non-FLAC data
- decode_truncated_flac_returns_zero: valid magic, truncated stream
- decode_empty_input_returns_zero: NULL source buffer
- decode_zero_length_returns_zero: non-NULL but zero-length source
- encode_zero_length_no_crash: NULL source, verifies no crash/leak
- encode_garbage_roundtrip_fails_cleanly: non-PCM encode + decode
- decode_dst_too_small_returns_zero: undersized output buffer

All tests are self-contained (no fixture files needed) and pass
under AddressSanitizer.
