// WebAssembly ENCODING TABLE (single source of truth)
// =============================================================================
//
// One form per mnemonic, indexed directly by the Mnemonic enum. Each entry
// records the prefix byte, the (sub-)opcode, and the immediate layout. The
// decode dispatch in decoding_tables.odin is derived from this table at
// package init, so opcode bytes are written down exactly once.
//
// The `mnemonic` field of each Encoding is left at INVALID here: the table
// index already identifies the mnemonic and the encoder never reads it back.
