feat(endpoint): initialize alknet-endpoint crate with all modules
- Create crates/alknet-endpoint/ with Cargo.toml, feature flags (quinn, iroh, tcp, acme)
- Implement HandlerRegistry (registry.rs) — extracted from core/endpoint.rs
- Implement AlknetEndpoint (endpoint.rs) — fresh build against ADR-083 shape
- new() takes no StaticConfig, no TLS config
- with_quinn/with_iroh/with_tcp_tls builder methods
- run() spawns accept loops for each active transport
- shutdown() is infallible (no Result)
- No EndpointError type
- Implement dispatch (dispatch.rs) — shared dispatch_connection free function
- Transport-agnostic: takes pre-extracted alpn, fingerprint, remote_addr
- ACME guard (acme-tls/1) behind acme feature
- build_auth_context resolves identity from fingerprint
- Implement accept loops:
- accept/quinn.rs — quinn accept loop with ALPN + fingerprint extraction
- accept/iroh.rs — iroh accept loop with ALPN negotiation + fingerprint
- accept/tcp_tls.rs — TCP+TLS accept loop (new code, not in old endpoint.rs)
- Add alknet-endpoint to workspace members
- All feature combos compile cleanly (no features, quinn, iroh, tcp, all three)
- Workspace cargo check passes
