Refactor Report

Summary

The runtime layer was refactored to restore the missing application startup API and make the project build successfully again.

What changed

• Added a runtime application container in src/runtime/application.rs with lifecycle support and shared runtime state.
• Added an application builder in src/runtime/builder.rs so the binary can construct the runtime through the expected builder pattern.
• Added lightweight runtime metrics support in src/runtime/metrics.rs.
• Updated the runtime module exports in src/runtime/mod.rs to expose the newly introduced components.
• Set the Rust toolchain to the installed stable toolchain so builds no longer fail due to an unconfigured default toolchain.

Verification

The changes were verified with:

export RUSTUP_TOOLCHAIN=stable-x86_64-unknown-linux-gnu && cargo build --release

Result:

• Build completed successfully
• Output ended with: Finished release profile [optimized] target(s) in 1m 16s

Notes

This refactor focused on restoring the expected runtime API surface with minimal, compatible implementations so the existing application entrypoint and build pipeline continue to function.
