io: Bump version to 0.4.0-rc.0
We updated a bunch of dependencies and forgot to re-release
`bitcoin-io`. And this is breaking the attempt at releasing `bitcoin
0.33.0-beta.0`.
Use RC because we have a dependency on `consensus_encoding` RC release
that uses the `=` syntax to pin the exact version. Therefore everytime
we do a new RC release of that crate we have to do `io` as well.
In preparation for release bump the version, add a changelog entry,
and update the lockfiles. Also update the version everywhere `io` is
used as a dependency including adding an explicit version number to
`p2p` (which will be needed to release it).

What changed, and why it matters
This commit is a routine version bump for a small Rust library called bitcoin-io, from version 0.3.0 to 0.4.0-rc.0. It updates lockfiles, a changelog, and dependency references in other crates so they all use the new version. There is no code change and no security issue visible in the commit.
Recommended action
No security action needed. Treat as normal release engineering.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The commit only changes version metadata: Cargo.lock files, io/Cargo.toml, io/CHANGELOG.md, and dependency declarations in bitcoin/Cargo.toml and p2p/Cargo.toml. The bitcoin crate and p2p crate now pin bitcoin-io with ‘=0.4.0-rc.0’ because the consensus_encoding RC dependency is pinned with ‘=’ syntax, requiring a matching io release. No source code, API, or behavior is modified.
