Closes #1911

Rationale for this change

What changes are included in this PR?

1. Enable -D warnings for Clippy in CI, and set workspace.lints = true for all sub-crates to align with unified workspace lint config.
2. Resolve auto-fixable lint issues via cargo clippy --fix.
3. Manually exempt existing panic-related code with the #[allow(clippy::panic)] annotation

Are there any user-facing changes?

Pull request overview

This PR enables stricter Clippy linting in the CI pipeline by switching from allowing all warnings to denying all warnings by default, while selectively allowing specific lints that require more extensive refactoring to fix. The PR also resolves many auto-fixable clippy warnings throughout the codebase and annotates existing panic-related code with #[allow(clippy::panic)] attributes.

Changes:

• Configure workspace-level lints with unwrap_used and panic denied, while temporarily allowing other lints that need gradual refactoring
• Update CI and build scripts to use cargo clippy --all-targets --workspace -- -D warnings instead of selectively denying only unwrap_used
• Apply auto-fixes for numerous clippy lints including needless_borrow, redundant_closure, needless_return, useless_format, uninlined_format_args, manual_range_contains, into_iter_on_ref, and others
• Add #[allow(clippy::panic)] annotations to existing panic-heavy code with comments indicating future refactoring plans
