chore: Release litep2p v0.13.0 (#522)

## [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.

### Added

- Add Bitswap client
([#501](#501))

### Fixed

- notif/fix: Avoid CPU busy loops on litep2p full shutdown
([#521](#521))
- protocol: Ensure transport manager knows about closed connections
([#515](#515))
- substream: Decrement the bytes counter to avoid excessive flushing
([#511](#511))
- crypto/noise: Improve stability of websockets by fixing AsyncWrite
implementation ([#518](#518))
- bitswap: Split block responses into batches under 2 MiB
([#516](#516))
- crypto/noise: Fix connection negotiation logic on partial writes
([#519](#519))
- substream/fix: Fix partial reads for ProtocolCodec::Identity
([#512](#512))
- webrtc: Avoid panics returning error instead
([#509](#509))
- bitswap: e2e test & max payload fix
([#508](#508))
- tcp: Exit connections when events fail to propagate to protocols
([#506](#506))
- webrtc: Avoid future being dropped when channel is full
([#483](#483))

 ## [0.12.3] - 2025-12-16
 
 This release improves the robustness of the multistream-select negotiation over WebRTC transport and fixes inbound bandwidth metering on substreams. It also enhances the dialing success rate by improving the transport dialing logic. Additionally, it re-exports CID's multihash to facilitate the construction of CID V1.
