1719: Rust Integration

[laert-ll]

This PR Fixes #1719

Continuation of #1827

• Updated Rust install flow to honor the explicitly requested version from CLI input (e.g. ide install rust1.1.0) instead of always resolving to the default release-0.7.
• Adjusted version resolution/normalization so requested Rust versions are used consistently for artifact lookup and installation.
• Improved install logging to show the effective Rust version being installed.
• Added regression coverage for:
• explicit version request behavior * fallback to configured default when no version is provided---
