New `dsl::ident_slot` module: IdentSlot enum with four variants — NewName (user invents), TableName (existing), Column (existing), RelationshipName (existing). Plus `completes_from_schema()` accessor for the completion engine in stage 8. Deliberate v1 simplification vs. ADR-0022 §8: no TableRef binding for Column. The completion engine in stage 8 will either union all columns or determine the table from the consumed prefix heuristically. The TableRef wrinkle returns if/when stage 8 needs it. Parser audit: renamed bare `ident()` → `ident_inner()` (now private-by-convention) and introduced `ident_ctx(slot)` wrapper. Every command parser combinator was audited and each `ident()` call site replaced with the appropriate `ident_ctx(IdentSlot::…)`: - create_table table-name → NewName - drop_table → TableName - add_column → TableName + NewName - drop_column → TableName + Column - rename_column → TableName + Column + NewName - change_column → TableName + Column - show_data / show_table → TableName - insert column-list → Column; insert table → TableName - update set-LHS → Column; update target → TableName - delete target → TableName - where-clause LHS → Column - relationship `as <name>` → NewName - drop relationship by name → RelationshipName - qualified_column → TableName + Column - with_pk_clause spec name → NewName The slot tag is currently documentation-only — the wrapper ignores it and returns ident_inner() unchanged. The audit's value is ensuring every call site has explicit intent recorded co-located with the parser combinator. The completion engine in stage 8 will start consuming the slots either by re-parsing with awareness or by an explicit parser-side propagation refactor. Tests: 700 passing, 0 failing, 1 ignored (698 baseline → +2 IdentSlot enum tests). Clippy clean. Stage 7 plumbs schema queries through the worker thread (ListNamesFor) so stage 8's completion engine has data.
