- same_tick_message_ordering_preserved: 20 numbered messages arrive in FIFO order
- send_payload_ptr_plus_len_overflow_traps: i32::MAX payload_ptr + 1 traps safely
- handle_sends_100_messages_in_one_call: 100 sends in single handle via loop
- br_table_dispatch_in_handle: switch-like dispatch on first payload byte
- Fixed prop_truncated_wasm_never_panics (renamed): test only asserts no-panic, not always-error
All 154 tests pass (10 property tests). No new bugs found.
