mDNS-style LAN discovery (iroh MdnsDiscovery, discovery flag, default
on) feeds a presence tracker; trusted peers that appear trigger fetches
of every incomplete pin, and Pin itself now fetches from present
trusted peers. Serving is our own ProtocolHandler: trusted NodeIds get
the full store, everyone else a filtered view limited to open_lan pins
and ticket-exported hashes (plus hashseq children) that answers "not
found" for the rest. Ticket export records standing serve-consent for
that hash; trust changes take effect on new connections. ShapedStore
implements the full iroh-blobs Store trait to charge provider reads to
an upload token bucket and downloader writes to a download bucket;
upload cap 0 closes incoming connections at accept. Subscribe now
streams transfer_progress both ways, peer_joined, and pin_complete.
Tests: forged-ticket trust gating (denied untrusted, served after
trust), 256 KiB/s upload cap enforced by wall clock, event stream
during a transfer, and real-mdns auto-sync between two daemons
(skips where multicast is unavailable).
Dependencies: n0-future, async-channel, futures-lite, bytes — all
already in the tree via iroh; needed directly to name types in
iroh-blobs trait signatures and channels. iroh feature
discovery-local-network for MdnsDiscovery.

The daemon binds an iroh endpoint (ed25519 identity at secret.key,
0600), serves its store via Blobs/Router on the standard ALPN, and
fetches with the iroh-blobs Downloader rather than the rpc client to
keep quic-rpc out of the tree. Relay is disabled unless wan_upload is
set: LAN-only, zero WAN upload by default. TicketImport pins first
(the pin is the GC root protecting in-flight data), registers the
ticket's NodeAddr with the endpoint (the downloader dials by NodeId
alone), then fetches in the background; completion emits pin_complete.
Tests: two-daemon localhost transfers (blob + directory collection,
byte-identical), and kill -9 mid-transfer followed by restart on the
same store resuming to completion.
Dependencies: iroh 0.35 (endpoint/router, pairs with iroh-blobs 0.35),
rand 0.8 (secret key generation, same version iroh uses).
