getLastChar used t[t.length-1] which only gets the trailing surrogate
of emoji like 🔚 (U+1F51A, a surrogate pair in UTF-16). This meant
end symbol matching ALWAYS failed for emoji symbols, causing every
non-humanList message to hit rule_match_no_end_symbol -> no-reply.
Fix: use Array.from(t) to correctly split by Unicode code points.
