Backport #10665 into stable2512 from lexnv.

See the documentation on how to use this bot.

## [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.

### Changed

- transports: Improves the robustness and success rate of connection
dialing ([#495](paritytech/litep2p#495))
- types: Re-export cid's multihash to construct CID V1
([#491](paritytech/litep2p#491))

### Fixed

- fix: multistream-select negotiation on outbound substream over webrtc
([#465](paritytech/litep2p#465))
- substream: Fix inbound bandwidth metering
([#499](paritytech/litep2p#499))

Contributor

This pull request is amending an existing release. Please proceed with extreme caution,
as to not impact downstream teams that rely on the stability of it. Some things to consider:

  • Backports are only for 'patch' or 'minor' changes. No 'major' or other breaking change.
  • Should be a legit fix for some bug, not adding tons of new features.
  • Must either be already audited or not need an audit.
Emergency Bypass

If you really need to bypass this check: add validate: false to each crate
in the Prdoc where a breaking change is introduced. This will release a new major
version of that crate and all its reverse dependencies and basically break the release.
