Start the ADR-0042 §1 near-miss matrix: a table-driven
near_miss_matrix_simple_mode locking 26 simple-mode parse-error
renderings (every DSL entry word's bare/missing-clause cases plus the
mode arg-errors and the "this is SQL" rail), and an #[ignore]
baseline_dump capturing the full rendering for ongoing triage.
G1 fix: the bare `1` cardinality literal that opens `add 1:n
relationship …` rendered cryptically in expected-sets. Render it as
`1:n relationship` in error wording only (format_expectation) —
completion/hints still read the raw Expectation::Literal("1"), so the
candidate surface is unchanged. Updated the one anchor test.
Full suite green (lib 1578 / it 382 / typing_surface_matrix 192).
