dig-store 0.5.1

The DIG Network DataLayer store manager: composes the on-chain CHIP-0035 DataLayer anchor (dig-merkle) with the off-chain .dig capsule format into one store abstraction — create/modify/melt a store coin (unsigned SpendBundles), a comprehensive on-chain getter surface, and the size proof that gates downloads on the on-chain-anchored size.

# Reusable CI gate (DIG-Network/dig_ecosystem#1469): fail a PR when Cargo.lock's own-package
# version drifts from Cargo.toml. Catches the stale-lock trap PRE-MERGE (a hand-bumped Cargo.toml
# version never synced into Cargo.lock passes normal checks but fails `cargo package --locked` at
# release/publish time -> red release). Pairs with the `--locked` flags in ci.yml. Byte-identical
# across every crate repo; the check script lives at scripts/check-lockfile-version.py.
