`tests/sql_select.rs` covers the full advanced-mode SELECT path
end to end (ADR-0030 Phase 1, ADR-0031):
App-level dispatch
- `advanced_mode_select_dispatches_as_command_select`: an
advanced-mode `select 1` produces exactly one
`Action::ExecuteDsl { command: Command::Select { sql }, .. }`
carrying the validated SQL text.
- `simple_mode_select_yields_sql_hint_and_does_not_dispatch`:
a simple-mode `select` produces no dispatch action and the
error output contains the SQL hint naming both recovery
paths (`mode advanced` / the `:` one-shot).
- `colon_one_shot_from_simple_mode_dispatches_select`:
`:select 1` keeps the persistent mode as `Simple` while
dispatching `Command::Select` with the `:` stripped.
- `advanced_mode_select_from_internal_table_is_rejected`:
a SELECT against `__rdbms_playground_columns` is refused by
the grammar's `reject_internal_table` validator.
Worker round-trip
- `database_run_select_constant_returns_a_single_row`:
`select 1` runs through `Database::run_select` and returns
a `DataResult` with one row whose only cell is `1`; all
`column_types` are `None` (ADR-0030 §6).
- `database_run_select_from_user_table_returns_inserted_rows`:
create-table → insert → `select Name from T` round-trips
the inserted row through the worker.
- `database_run_select_appends_to_history_when_source_present`:
the literal source line lands in `history.log` so replay
re-runs it (ADR-0030 §11).
