Implement ADR-0025 — indexes as a DSL DDL feature. - Grammar: `add index [as <name>] on <T> (<cols>)`, `drop index <name>` / `drop index on <T> (<cols>)`, plus a `--cascade` flag on `drop column`. - db.rs: index operations over the engine's native index catalog (no metadata table). The rebuild-table primitive now captures and recreates indexes, so `change column` and the relationship operations no longer silently drop them. - `drop column` refuses an indexed column unless `--cascade`, which drops the covering indexes and reports each. - Persistence: additive `indexes:` list in `project.yaml` (version unchanged); round-trips through rebuild/export/import. - Display: an `Indexes:` section in the structure view and a nested tables/indexes items panel (S2). Reconciles requirements.md (C3 index portion, S2 satisfied) and CLAUDE.md. 1038 tests passing (+31), clippy clean.
