• Maintenance: Keeps the dependency up to date with the latest stable version.

Changes

• Updated regex version in implants/Cargo.toml.

Verification

• Ran cargo check and confirmed the dependency tree resolves correctly.
• Ran cargo build --all-targets (passed).
• Ran cargo test --all-targets (passed, with unrelated known failures in imix tests).
• Confirmed implants/Cargo.lock is git-ignored.
