fix: clippy errors with new config (#4428)

* refactor: improve code quality with clippy fixes and standardized logging

- Replace dangerous unwrap()/expect() calls with proper error handling
- Standardize logging from log:: to logging\! macro with Type:: classifications
- Fix app handle panics with graceful fallback patterns
- Improve error resilience across 35+ modules without breaking functionality
- Reduce clippy warnings from 300+ to 0 in main library code

* chore: update Cargo.toml configuration

* refactor: resolve all clippy warnings
- Fix Arc clone warnings using explicit Arc::clone syntax across 9 files
- Add #[allow(clippy::expect_used)] to test functions for appropriate expect usage
- Remove no-effect statements from debug code cleanup
- Apply clippy auto-fixes for dbg\! macro removals and path statements
- Achieve zero clippy warnings on all targets with -D warnings flag

* chore: update Cargo.toml clippy configuration

* refactor: simplify macOS job configuration and improve caching

* refactor: remove unnecessary async/await from service and proxy functions

* refactor: streamline pnpm installation in CI configuration

* refactor: simplify error handling and remove unnecessary else statements

* refactor: replace async/await with synchronous locks for core management

* refactor: add workflow_dispatch trigger to clippy job

* refactor: convert async functions to synchronous for service management

* refactor: convert async functions to synchronous for UWP tool invocation

* fix: change wrong logging

* refactor: convert proxy restoration functions to async

* Revert "refactor: convert proxy restoration functions to async"

This reverts commit b82f5d250b2af7151e4dfd7dd411630b34ed2c18.
