Pull request overview

This PR bumps the rspack version from 1.6.5 to 1.6.6, updating all package versions across the monorepo consistently. The release follows the project's versioning convention where JavaScript packages use 1.x.x semver while Rust crates use 0.x.x, keeping minor and patch versions synchronized.

Key Changes

• JavaScript packages updated from 1.6.5 to 1.6.6
• Rust workspace version updated from 0.6.5 to 0.6.6
• All 88+ internal Rust workspace dependencies updated to use exact version =0.6.6
