Pull Request Overview

This PR standardizes dependency versions across the workspace and ensures benchmark builds use the lockfile for consistent measurements.

• Added --locked to all CanBench build_cmd entries to remove noise from benchmark outputs
• Migrated many crate dependencies to workspace-managed versions and bumped key versions (e.g., serde, ic-cdk, candid)
• Reorganized per-example Cargo.toml files to use *.workspace = true where appropriate
