Bump MSRV from 1.61.0 to 1.88.0

[gcomte]

Summary

• Dependencies already require Rust 1.88.0+ (verified via cargo msrv find). The declared MSRV of 1.61.0 was inaccurate.

Test plan

• cargo check passes
• CI build passes

Summary by CodeRabbit

• Chores
  • Updated the minimum supported Rust version requirement to 1.88.0.

📝 Walkthrough

Walkthrough

The minimum supported Rust version (MSRV) in Cargo.toml has been updated from 1.61.0 to 1.88.0. This adjustment reflects the crate's compatibility with newer Rust toolchains and may enable the use of language features introduced in those intermediate versions.

🐰 A version bump hops into view,
From sixty-one to eighty-eight we flew!
Rust grows stronger, so do we,
Modern features now are free,
The compiler's path shines bright and new! ✨

7-7: Consider adding MSRV verification to CI.

While the MSRV update is correct, the CI workflows currently test against stable and nightly toolchains but not the declared minimum version. This means the MSRV guarantee isn't verified in CI—if code inadvertently uses features from Rust > 1.88.0, it won't be caught until someone tries to build with the minimum version.

Consider adding a CI job that builds and tests with Rust 1.88.0 to ensure the MSRV claim remains accurate:

msrv_check:
  name: Check MSRV
  runs-on: ubuntu-latest
  steps:
    - uses: actions/checkout@v2
    - name: rust-toolchain
      uses: actions-rs/toolchain@v1.0.6
      with:
        toolchain: 1.88.0
        override: true
    - name: Check
      run: cargo check --all-features

As per coding guidelines, the workflows .github/workflows/code-analysis.yml and .github/workflows/build.yml use toolchain: stable which does not verify the MSRV of 1.88.0 declared in Cargo.toml.
