Comments help non-Rust users understand what each function, struct, and
module does. Covers the core service (18 source files) and all four
example projects (can-sync, canfs, filemanager, paste).

Peers sharing the same sync_passphrase can now find each other
automatically over the internet without manual ticket exchange or
port forwarding. Uses n0's public pkarr relay servers as a
rendezvous point.
How it works:
- Derive 8 deterministic Ed25519 keypair "slots" from the passphrase
- Each peer claims a slot by publishing its EndpointId as a TXT record
- All peers scan all 8 slots every 15s to discover new peers
- Re-publish every 60s with 5min TTL to stay visible
- Discovered EndpointIds feed into the same peer channel as gossip
This runs alongside the existing gossip discovery (which still needs
bootstrap peers) and direct ticket-file connections (used by tests).
All 6 stress tests pass (102 assets, 63+ MB/s bidirectional).
