fix: vet fallback emoji — verb gate + expanded stop list removes 852 bad matches

The fallback emoji system (keyword→Unicode char matching at build time)
was producing 1,733 matches, many with wrong-sense emoji:
- "high, tall" → ⚡ (from "high voltage")
- "to cut" → 🥩 (cut of meat)
- "city" → 🇻🇦 (Vatican flag)

Two fixes:
1. Skip fallback for verbs (meanings starting "to ") — 476 removed
2. Expand _EMOJI_STOP with 100+ polysemous/abstract keywords — 376 more

Result: 1733 → 881 fallback matches (49% reduction). The 114 from_pealim
emojis (concrete nouns like 🍎 apple, 🐪 camel) are unaffected.
