What happened?

changedset in scripts/js/release-metadata.mjs reports StoreFactory as changed when only a comment changed in a contract it deploys. StoreFactory's code is identical in both builds.

Affected contract: StoreFactory, the only contract in contracts/ that deploys others with new.

Expected behavior

changedset reports a contract only when its code changed, so a comment-only edit never makes a release require a StoreFactory upgrade.

Reproduction

1. On a clean checkout, run forge build, then node scripts/js/release-metadata.mjs build --tag base --out /tmp/base --addresses false.
2. Change a comment in contracts/store/LabelStore.sol.
3. Run forge build, then node scripts/js/release-metadata.mjs changedset --previous /tmp/base/codehashes.json.
4. StoreFactory is listed.

Additional context

• Found in feat: rename lite/full to device and personhood names, with legacy gateway entrypoints #321, whose NatSpec-only edits to LabelStore.sol and ILabelStore.sol put StoreFactory in its changedset.
• changedset ignores the metadata solc appends to a contract's bytecode, but only StoreFactory's own. The creation code of LabelStore, UserStore, UpgradeableBeacon and BeaconProxy is embedded in StoreFactory's bytecode, each copy with its own metadata, and those copies still count.
• The codehashes.json attached to every release carries the same hashes, so comparing two releases' files gives the same result.
