Ci/restore smoke ci

📝 Pull Request Summary

Description

This PR addresses Issue #651 by restoring the essential smoke-ci verification workflow framework. This pipeline was accidentally dropped in past repository housecleaning sweeps (chore(ci): delete smoke workflow / chore(ci): remove failing ci.yml). It re-establishes a deterministic quality baseline that must pass cleanly on all cross-branch merges.

Key Modifications

• PR Integration Target: Introduced .github/workflows/smoke-ci.yml listening cleanly to any inbound pushes or incoming merge request modifications aimed at critical operational target branches (main, master, develop).
• Multi-Stage Code Screening Grid:
  • cargo fmt --check: Restricts malformed text and spacing setups from leaking layout inconsistencies into code reviews.
  • cargo clippy: Enforces idiomatic patterns and elevates standard lint warnings into strict build failures (-D warnings).
  • cargo test: Automatically executes all test targets across workspace modules to maintain overall code health.
• Smart Dependency Caching: Configured an updated, isolated caching policy for Cargo directories to optimize compilation speeds.

Closes #651
