Module pool 

The pool command arms (ADR-051 D1;).

Ports cli/pool.py arm for arm:

• pool update — the chunk-loop hand-off to run_pool_update, with the --chunk / --to-block / --verify-chunk / --verify-all / --verify-all-interval flags 1:1. Progress stays a no-op sink here (ADR-051 D9: the bin paints it); a cooperative cancel returns a friendly cancelled report (exit 0), matching the Python RuntimeError guard.
• pool verify — the read-only, ad-hoc sibling: fetch the COMMITTED liquidity map, compare against on-chain truth at --block, and render GREEN / the named divergence list.
