Commit Message

chore(ci): switch rust toolchain to stable (#7524)

Description
switch rust toolchain to stable

Motivation and Context
use stable rust toolchain


<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->

## Summary by CodeRabbit

* **Chores**
* Standardized Rust toolchain on stable across CI workflows for more
predictable builds.
* Streamlined setup by removing unnecessary components and aligning
toolchain configuration with environment variables.
  * Enabled an environment flag to improve rustup behavior during CI.
* Improved coverage workflow consistency with dynamic toolchain
selection.

* **Tests**
* Removed nightly-only requirements, simplifying test commands and
improving compatibility.
* Expanded CI triggers to include ci-* branches for better pre-merge
validation.
* Maintained existing job logic while improving reliability and
maintainability.
