Both forms came in with the codegen split (#91) but no [[vpn]] rule has ever used them — the only `suffix=` rules are `digits` (`wlan` test vector + `if` from #93). The grammar surface paid for itself in ~150 lines of dead C/Rust helpers + their tests. Drop them from VALID_KINDS, the parser, the C/Rust/Kotlin emitters, and the helper test cases. If a future rule needs either form, reintroduce alongside the rule that needs it. Re-ran the codegen; tests pass for all four targets.
