 * License identification using Dice coefficient on bigrams.

 * Similarity is separate from whether the normalized text matches exactly. The
 * original license texts are only needed when generating the corpus.
 *
 * Handles:
 *
 * - Canonical SPDX / vendor URLs embedded in pointer-style license files
 * - Standard license texts (MIT, BSD, Apache, etc.)
 * - GNU family licenses via header pattern matching (LGPL, AGPL)
 * - Markdown-formatted license files (strips headings, tables, links)
 * - YAML front matter stripping
