v1.6.0 - Pronunciation Guide, A&G Cross-Reference Links

What's new

• Pronunciation Guide reference entry. Five tables (Vowels, Nasalized Vowels, Diphthongs, Consonants, Geminates) map this dictionary's own reconstructed IPA onto real example words in English, German, French, Italian, Spanish, and Icelandic wherever a genuinely close sound exists — a language is left out of a row rather than forced onto an approximate match it doesn't have. A 7th column, Ecclesiastical Latin (the still-living Italianate pronunciation tradition), appears only where it instructively diverges from Classical (c/g before e/i, v, gn, the aspirated-stop mergers). Geminates are checked against this project's own 51,636-headword corpus rather than assumed — every consonant included is genuinely productive in real Latin spelling. Icelandic examples were corrected against a primary source and native-speaker verification (pabbi/dögg/saddur), and excluded from the pp/tt/kk rows specifically, since Icelandic realizes that contrast via preaspiration rather than plain held length.
• Allen & Greenough's own cross-references are now clickable. A&G's TEI source contains 1,144 <ref n="NNN"> cross-references, previously rendered as plain unclickable text. These now become real x-dictionary: links wherever the target is one of this project's own indexed grammar entries (172 qualify) — the rest correctly stay plain text rather than becoming dead links, since only "named rule" topics (like "Ablative Absolute"), not every section's running prose, get their own citation-indexed entry.

Regression coverage

scripts/test_dictionary.py gained checks for both features: the Pronunciation Guide's structure, content, and Icelandic-specific corrections, and the A&G ref-linkification's validate-before-linking behavior.
