update MSRV to 1.74 everywhere except in internals
If I update it in internals, our uses of `rust_version!` with values below
1.74 break. In particular the cond_const! macro breaks. So I will do that
in the next commit, so the diff for this one is simple.
We may want to put some work into getting a single source of truth here...
I had to change this constant in 29 files, plus internals/Cargo.toml.

What changed, and why it matters
This commit is a routine maintenance change that raises the Minimum Supported Rust Version (MSRV) from Rust 1.63.0 to 1.74.0 across documentation, CI configuration, and package manifests. It does not change any code logic, cryptographic operations, or security behavior. It simply tells users and automated tooling that the project now requires a newer Rust compiler.
Recommended action
No security action required. Treat as a normal dependency/toolchain policy update. Users building from source should ensure their Rust toolchain is at least 1.74.0.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The commit updates rust-version fields in Cargo.toml files, README badges/text, clippy.toml, and the GitHub Actions CI matrix from 1.63.0 to 1.74.0. No source code, dependencies, features, or APIs are modified. The commit message explicitly notes this is a simple MSRV bump and that internals/Cargo.toml is intentionally left for a follow-up commit to avoid breaking cond_const!/rust_version! macros. There is no security patch or vulnerability fix present in the diff.
