050 kebab event emits

// PIN (kebab-stdlib-restructure): a kebab event name must MANGLE to `-`→`_` on
// emission (Zig: `my_event`), not leak raw. RED today — the name parses but
// emission leaks `pub const my-event_event = struct` → invalid Zig. The real
// Track-B work is the emit mangle, not parser acceptance.
