F1: the hint panel is the completion UI, so a premature "no such table/
column" ERROR on the token the user is still typing must not shadow its
completion. ambient_hint now suppresses an under-cursor error diagnostic
when a completion exists for the (non-empty) partial it overlaps, and
falls through to the candidates. Genuinely-unknown names (no prefix match)
still show the error; WARNINGs are unaffected. Both modes.
F2: projection-before-FROM ("select <cursor> from T" after deleting *)
offered the global column list instead of T's columns, because the §10.6
look-ahead's full-input walk can't reach FROM through an empty projection.
When the look-ahead finds no scope, retry with a neutral placeholder
inserted at the cursor so the trailing FROM/CTE scope is recovered for
narrowing. Only the repaired walk's from_scope/cte_bindings are used.
Test-first: 3 F1 tests (mid-typed completes, unknown still errors, simple-
mode DSL) + 1 F2 multi-table narrowing test. 1469 baseline green.
