Make bundled mode actually self-contained: resolve() now leads the relay set with GP_BUNDLED_RELAY_URL (default ws://127.0.0.1:7777), which the checkout nprofile advertises, so a merchant needs no third-party relay. External mode uses only GP_RELAYS. Ship the relay as a vendored, unmodified nostr-rs-relay config (deploy/relay/nostr-rs-relay.toml); the compose service arrives with the deploy pipeline. Fix the stale "bundled is a later milestone" comment and reconcile the GP_NYM=off wording to a supported server-side-clearnet posture.
A self-hostable Grin payment server for shops, creators, and sites: show a
code, Grin lands in your wallet, with a verifiable Grin payment proof on
receive. Workspace crates (gp-core / gp-nostr / gp-server / gp-wallet /
gp-goblin-sender), a WooCommerce connector, a hosted /pay/<token> checkout,
and NIP-44 v3 gift-wrapped payment DMs carried over the Nym mixnet. All
secrets are read from the environment; none are committed.
