itd-16 calls bare-command-as-help a universal convention; the surfaces register says bare invocation is a convention, not a universal

A terminology drift (severity nitpick) found by the cross-document consistency pass.

• End A: .abcd/development/intents/drafts/itd-16-hash-chain-merkle-audit.md:49 — "status+help only per the universal bare-command-as-help convention"
• End B: .abcd/development/brief/04-surfaces/README.md:227 — "It is a convention rather than a universal, and the exceptions are where the tree does not yet meet its own discipline."

itd-16 justifies bare /abcd:audit by 'the universal bare-command-as-help convention'. The surfaces register says bare invocation is a convention rather than a universal, that it renders state rather than help, and that its exceptions are listed in one place. The two documents mean different things by the bare-invocation rule.
