chore: Release litep2p v0.13.0

[dmitry-markin]

[0.13.0] - 2026-01-21

This release brings multiple fixes to both the transport and application-level protocols.

Specifically, it enhances WebSocket stability by resolving AsyncWrite errors and ensuring that partial writes during the negotiation phase no longer trigger connection failures.

At the same time, Bitswap client functionality is introduced, which makes this release semver breaking.
