render_input_runs now overlays the walker's schema-aware diagnostics: an unknown table/column ERROR is recoloured tok_error, an expression WARNING (type mismatch, = NULL, LIKE on a numeric column) recoloured theme.warning. New overlay_span covers a token's whole byte range (overlay_error only hits the run at a single byte). New walker::input_diagnostics is the shared entry point. The overlay is global — every flagged token is coloured wherever it sits, not only under the cursor — which is exactly ADR-0027's motivation. The existing cursor-local invalid-ident overlay is kept (it covers in-progress idents diagnostics do not); the two are additive and idempotent. 5 input_render tests (unknown table/column, type-mismatch literal precise, LIKE-on-numeric, clean command). 1113 passing, clippy clean.
