Replace the generic lexer mode array with active formatted-string frames. Carry raw-string context with emitted and cached parser tokens, so token interpretation remains correct after the lexer advances.
Keep expression entry, punctuation, closing, and debug-expression transitions together in the string scanner, with explicit dispatch over its three modes.
Depends on #138.
