`Cargo.toml`: add `column_metadata` to rusqlite's feature list. This pulls in the SQLite `SQLITE_ENABLE_COLUMN_METADATA` compile flag and surfaces `sqlite3_column_table_name` / `sqlite3_column_origin_name` on prepared statements via rusqlite's `Statement::columns_with_metadata()`. `do_run_select` in db.rs now calls a new `resolve_select_column_types(conn, stmt)` helper after `prepare`. The helper walks each result-column's origin metadata; when both `table_name` and `origin_name` come back populated (the result column traces back to a base-table column), it looks up the playground type in `__rdbms_playground_columns`. The per-column types thread through to `format_cell(value, ty)` so the data-table renderer (ADR-0016) gets the same per-type rendering it applies to `show data` results. Effect: ADR-0030 Phase-1 §4.5 (bool SELECT results render as `0` / `1`) is lifted for any bare-column reference whose origin the engine carries through — per ADR-0032 Amendment 1 (2026-05-20 empirical probe), that means all non-recursive CTE bodies, scalar subqueries (aliased or not), derived tables, set ops, and JOINs. Computed projections and recursive-CTE result columns remain typeless (the engine populates no origin), which the renderer handles via neutral alignment. The lookup is engine-driven verbatim — no grammar-side structural classification (ADR-0032 Amendment 1 replaces §12's original "structurally a single column reference" rule with "trust column_table_name / column_origin_name"). Tests (3 new in `tests/sql_select.rs`, all green): - `database_run_select_recovers_bool_column_type` — the Phase-1 §4.5 case: `SELECT Active FROM Products` returns `column_types = [Some(Bool)]` and rows render as `true` / `false`. - `database_run_select_recovers_text_type_through_alias` — `SELECT Name AS n FROM Users` remaps the result column name to `n` but the origin metadata still resolves the playground type to `Some(Text)`. - `database_run_select_computed_expression_stays_typeless` — `SELECT Score + 1 FROM T` keeps `column_types[0] = None`, the documented Amendment-1 exception. The CTE pass-through, scalar subquery, set-op, and JOIN cases all work for free given the empirical findings; their behaviour is asserted by the Amendment-1 probe results recorded in the ADR, so no per-case integration tests are duplicated here. Test totals: 1382 → 1385 passing (+3), 0 failed, 1 ignored. Clippy clean.
