Phase 3 wiring (task #12):
- NostrSeedDiscovery: async ProviderDiscovery that queries relays for signed
seed adverts and parses endpoint ids (swarm/iroh_provider.rs, seed_advert.rs).
- seed_and_advertise publish path; dep-free fetch/publish helpers reuse the
node's Nostr identity (build_nostr_client/load_or_create_nostr_keys made
pub(crate)).
- swarm::init builds the IrohProvider once into a OnceLock runtime; providers()
returns it; announce_held_blob() is called from update.rs after a release
component passes both hash gates.
- config swarm_enabled (ARCHIPELAGO_SWARM_ENABLED, default off); server.rs init.
Paid swarm serving (Phase 4 step F):
- swarm/paid.rs gates the iroh-blobs provider through streaming::gate,
intercepting connect + GET (peer push hard-disabled). Free by default
(content-download service disabled); denies unpaid peers when enabled;
fails open on internal error so a payment fault never blocks distribution.
Wired into IrohProvider::new.
All iroh code behind the iroh-swarm feature; the default build is inert.
Default build clean; --features iroh-swarm: 11/11 swarm tests pass.

The discovery wire format that feeds the swarm's ProviderDiscovery seam: a
node announces 'I seed blake3 H from iroh endpoint E' as a signed NIP-33
addressable Nostr event. Scope is releases/catalog content ONLY (decided
2026-06-16) — never private user blobs.
- swarm/seed_advert.rs: kind 30081, d-tag = blake3 hex (one current advert
per author+hash, latest-replaces), content {"v":1,"endpoint_id":...}.
advertisement_builder / advertisement_filter / parse_endpoint_id /
endpoint_ids_from_events (dedup). Endpoint ids stay opaque strings so the
protocol is dep-light + unit-testable on the default build.
4/4 tests pass (sign->parse roundtrip, filter targeting, reject wrong-kind/
empty, dedup across nodes).
Next (task #12): gated NostrSeedDiscovery glue (query relays, parse ids ->
iroh::EndpointId), publish path, wire swarm::providers().
