/**
 * Formula Calculation Implementation
 *
 * The pipeline that implements the snapshot → compile → evaluate →
 * materialize → apply architecture.
 *
 * ## Pipeline Steps
 *
 * 1. **Snapshot** — `buildWorkbookSnapshot()` creates an immutable snapshot
 *    of the entire workbook.
 * 2. **Normalize** — `collectFormulaInstances()` extracts all formula cells
 *    into uniform `FormulaInstance` objects.
 * 3. **Parse** — Each formula's source text is tokenized and parsed into an AST.
 * 4. **Compile** — The binder transforms each AST into a `BoundExpr` tree,
 *    resolving names, structured references, and sheet references.
 * 5. **Dependency Analysis** — Static dependencies are extracted from bound
 *    expressions and a topological evaluation order is computed.
 * 6. **Evaluate** — Formulas are evaluated in dependency order using the
 *    evaluator which operates on `BoundExpr` and produces `RuntimeValue`.
 * 7. **Materialize** — Evaluation results are converted into a `WritebackPlan`.
 * 8. **Apply** — The plan is applied to the live workbook.
