kglite 0.10.9

//! Top-level extraction orchestrator.
//!
//! `run_all(workdir, slice, force)` is the single entry point for
//! every extraction run:
//!
//! 1. Open every sink (`Sinks::open`) — writes 34 CSV headers up front.
//! 2. Load identity tables from `submissions.zip` (one upfront pass).
//! 3. Call each `forms::*::extract` in turn. Each form module writes
//!    info rows into the appropriate sinks and updates identity-table
//!    dedup sets.
//! 4. Flush all sinks, emit the SIC index, return the run report.
//!
//! Idempotency: if `force == false` and the processed/ directory
//! already contains a `holding.csv` (canonical sentinel for "this
//! extractor has been run"), the orchestrator returns early. Pass
//! `force == true` to re-extract.
//!
//! ## On adding a new form
//!
//! 1. Add the form's module under `forms/`.
//! 2. Add its CSV header(s) + Sinks field in `sinks.rs`.
//! 3. Add a dispatch call in `run_all` below.
//!
//! That's it. No PyO3 changes, no wrapper.py changes.
