Two independent traps. The noise filter only keeps word tokens right
after a conversion token (in/as/...); any other token type resets
that, so the "/" in a slash-form IANA id ("Europe/Berlin") reset it
before the parser ever saw "Berlin". The word-collecting loop in
parseTarget() had the same blind spot even once the token was there.
Both needed the same exception, or "Europe/Berlin" still degrades to
just "Europe".
- vocab: EN+RU aliases for abs/log/ln/round; RU already had sqrt/cbrt
- engine: "half"/"a half"/"one half"/"половина" → 0.5; "one and a half"/"полтора"/"полторы" → 1.5 as named constants; widen const union in parser/tokenizer/evaluator/registry
- export: ⤓ button in statusbar dropdown — copy sheet, save .sum, export .txt, print/PDF; write_text_file Tauri command; print media CSS hides chrome
Write plain text, get live results per line. English + Russian, units,
