feat(enhance): add pluck/raw/expand statement modes

Add better-sqlite3-compatible statement modes to enhance():
- pluck(): return first column value only
- raw(): return rows as arrays
- expand(): return rows namespaced by table
- stmt.database: back-reference to parent db

Modes are mutually exclusive, matching better-sqlite3 toggle semantics.
Expand mode uses arrays internally to handle duplicate column names.

+### Added
+
+- **Statement modes via `enhance()`**: `stmt.pluck()`, `stmt.raw()`, `stmt.expand()` for better-sqlite3 compatibility
+  - `.pluck()` returns only the first column value from queries
+  - `.raw()` returns rows as arrays instead of objects
+  - `.expand()` returns rows namespaced by table, correctly handling duplicate column names across JOINs
+  - All three modes are mutually exclusive, matching better-sqlite3's toggle semantics
+- **`stmt.database`**: Back-reference from prepared statements to their parent database instance
+- **`EnhancedStatementMethods` type**: TypeScript interface for `pluck()`, `raw()`, `expand()`, and `database`
