Pin RELEASE_ROOT_PUBKEY_HEX from the 2026-07-02 release-root signing ceremony
(signer did🔑z6MkkidEnEpo6qHMCNSZoNKWtvQvxq3whnaME9wGgEFhq7ur) so nodes verify
the publisher identity of the app-catalog. Sign releases/app-catalog.json in place.
Fix two floats that made the catalog unsignable: archy-btcpay-db manifest version
-> string, fedimint-clientd cpu_limit 0.25 -> 1 (u32). Add scripts/sign-catalog.sh
helper, the 1.8.0 release-hardening plan/tracker, and the commit-and-push project
rule in CLAUDE.md.
Backward-compatible: old binaries still accept the signed catalog; the pinned-anchor
binary ships in the next build/OTA.
