What changed in this PR

Prevents Dependabot from updating dtolnay/rust-toolchain, preserving the pinned minimum supported Rust version (MSRV) test while existing stable jobs continue tracking new compiler releases.

Changes:

  • Adds a Dependabot ignore rule for dtolnay/rust-toolchain.
  • Documents that MSRV increases should be coordinated with Cargo.toml’s rust-version.
File Description
TESTING.md Clarifies stable compiler coverage and deliberate MSRV updates.
.github/​workflows/​actions.yml Adds a comment explaining the MSRV pin; workflow behavior is unchanged.
.github/​dependabot.yml Ignores updates to dtolnay/rust-toolchain to preserve the MSRV pin.
