Re-release without rc suffix
Turns out that the `-rc.0` suffix causes way more problems than it
solves because of how `cargo` resolves the version numbers and what we
intended on using the RC releases for.
In brief
- We wanted to be able to do breaking changes if required
- We wanted to signal that these releases were almost there (TM)
- We wanted to be able to do downstream testing including releasing
downstream crates with the RC releases as part of their public API.
In hindsite we messed up and should have just kept iterating as normal
until we were ready.
Re-release the whole stack without any rc suffix's. However keep
`bitcoin 0.33.0-beta` because we want 0.32.0 to be the latest stable
release and its important that it shows as such on docs.rs
Also, for pre-1.0 crates that had an rc release just jump to the next
version i.e., `io 0.4.0-rc.0` goes to `io 0.5.0`. Just for good
measure.

What changed, and why it matters
This commit is a routine release-management change for the rust-bitcoin project. It re-releases several crates without the '-rc' (release candidate) suffix in their version numbers and updates internal dependency version requirements accordingly. There are no code logic changes, bug fixes, or security patches in the diff—only version numbers, lock files, changelogs, and README text.
Recommended action
No security action required. Treat as a normal release/versioning update. Downstream users should verify that the new pre-1.0 version numbers and relaxed dependency constraints are compatible with their own Cargo version requirements, but this is a dependency-management concern, not a security issue.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The commit changes Cargo.toml version fields and dependency constraints across the workspace: bitcoin-consensus-encoding 1.0.0-rc.3 → 0.1.0, bitcoin-units 1.0.0-rc.4 → 0.3.0, bitcoin-primitives 1.0.0-rc.2 → 0.102.0, bitcoin_hashes 0.19.0 → 0.20.0, bitcoin-io 0.4.0-rc.0 → 0.5.0, base58ck 0.3.0 → 0.4.0, and bitcoin 0.33.0-beta.0 → 0.33.0-beta. It removes the ‘=’ exact-version pins on consensus_encoding, io, primitives, and units dependencies. Cargo.lock files and changelogs are updated to reflect the new versions. No source-code behavior is modified.

+semver trick as possible in subsequent releases to assist downstream
