• Capture raw message for invalid-format validation errors — invalid-format is now the dominant file-validation-error bucket (52%), but the bucket alone doesn't distinguish between datareader.bf alphabet/structure errors, +page.svelte fallback messages, and FastaValidator parser errors. Attach a truncated raw message to invalid-format events so we can split the bucket properly. (#134)
