Fix: Apply rustfmt formatting to resolve CI pipeline failures

[Copilot]

The GitHub Actions CI pipeline was failing on the formatting check step with cargo fmt --all -- --check. This PR resolves the issue by applying proper Rust formatting to all source files.

Problem

The CI workflow includes a formatting verification step that runs:

cargo fmt --all -- --check

This command was failing because multiple source files had formatting inconsistencies including:

• Trailing whitespace in comments
• Incorrect import ordering and grouping
• Inconsistent spacing around operators and method calls
• Missing line breaks and improper indentation

Solution

Applied cargo fmt --all to automatically format all Rust source files according to rustfmt standards. The changes are purely cosmetic and include:

• Import statement reordering and proper grouping
• Consistent spacing and indentation
• Removal of trailing whitespace
• Proper line breaks for readability

Files Modified

• src/analyzer/mod.rs, src/analyzer/rust.rs
• src/cache/mod.rs, src/config/mod.rs
• src/domain/mod.rs, src/domain/violations.rs
• src/lib.rs, src/main.rs
• src/patterns/mod.rs, src/patterns/path_filter.rs
• src/report/mod.rs

Verification

• ✅ cargo fmt --all -- --check now passes
• ✅ All 51 tests continue to pass
• ✅ Code builds successfully with no functional changes

Fixes #10.
