Diagnostics no longer repeat the generated table's ignorance of a
registered mnemonic: unknown-instruction and unencodable-instruction
against a statement the registry encodes are filtered from the server's
own presentation, driven by asm.LookupExtension directly. The filter is
a no-op once lint learns the registry, so the two compose unchanged.

Completion merges the extension registry's mnemonics beside the toolchain
entries, with operand shapes measured against the layer's own encoder, and
hover documents a registered mnemonic from its metadata: the extension
notice, the forms, the features, the fixed encodings and the manual
references.
