v0.1.0-beta.30

Improvements

• Expand file-validation-error telemetry classifier — 43% of file-validation errors were landing in the unknown bucket, hiding the actual failure modes from analytics. Added new buckets (wrong-alphabet, dataset-too-large, insufficient-sequences, runtime-error) and broadened invalid-format to catch datareader.bf and FastaValidator messages that don't contain the literal word "format". The remaining unknown events now include a truncated raw message so future slip-throughs are debuggable. (#133)
