Sources: endoflife.date cycles (python/go/rust/kotlin), Adoptium feature
releases (java), r-hub minors (r); ISO standards / language versions hardcoded
for c/cpp/csharp/dart (no clean feed). --keep caps each fetched list (Rust's
6-week cadence alone is ~70 cycles). Fails loudly (exit 69) rather than writing
a partial catalog.

dart run halkyon_curator:language_versions
--output ../halkyon-learn/assets/language_versions.json

Generates the bundled language_versions.json catalog that halkyon-learn's code-notebook version picker reads. Unlike the other curators (which emit importable .halkyon content), this one emits app config — the first of its kind here.
