feat(core): migrate iroh 0.35 -> 1.0.2

Cargo.toml: iroh = { version = "1.0", optional = true, default-features = false, features = ["tls-aws-lc-rs"] }

6 API changes in endpoint.rs + types.rs:
- Endpoint::builder() -> builder(presets::Minimal) (mandatory crypto_provider)
- SecretKey::from_bytes() now returns SecretKey directly, not Result
- SecretKey::generate() takes no rng arg (OsRng internal)
- Connection::remote_node_id() -> remote_id() (returns PublicKey, not Result)
- Connection::alpn() returns &[u8] directly, not Option<&[u8]>
- tls-aws-lc-rs feature matches quinn path's existing crypto provider

Unblocks alknet-blobs (depends on iroh-blobs 0.103 which pulls iroh 1.0
transitively). See docs/research/iroh-update/findings.md for the full trace.
