Replaces the originally-planned separate ADRs for syntax highlighting (I4) and tab completion (I3) with a single unified design. The framing: colour, hint panel, and Tab are three answers to the same question — what does the user need to know mid-typing? — and planning them separately produces three loose pieces that drift apart. Three mid-typing states (valid-so-far / definite-error / incomplete-but-plausible) drive four layered channels: token-class colour and parse-error overlay (silent, always on), hint panel ambient and Tab-triggered completion mode (verbose, in the existing hint panel — no floating popups). Schema-aware from day one via an IdentSlot taxonomy in the parser (NewName / TableName / ColumnIn(TableRef::Earlier(N)) / RelationshipName); every existing ident() call gets audited and tagged. Completion candidates come from chumsky's expected-token-set for keyword slots and from a new worker request (ListNamesFor) for identifier slots. Implementation lands in 8 green-after-each commits: theme colours; input panel highlighting; echo line highlighting; render-time parse + error overlay; hint panel ambient; identifier-slot taxonomy + parser audit; schema query plumbing; completion mode + key bindings. Estimated 1500-2500 lines across the eight stages. Out of scope (deliberately): inline ghost text (could return as a "most-likely" affordance later — fish-shell style), fuzzy matching, punctuation completion, user-customisable keybindings, SQL highlighting in advanced mode (waits on Q4).
