chore: pin serde_json to GCP SDK compatible version

Pin serde_json to 1.0.132, the minimum version required by Google Cloud
Platform Storage SDK.

## Changes
- runtime/Cargo.toml: Pin serde_json to "1.0.132"
- Cargo.lock: Updated to use compatible version (1.0.145)

## Rationale
- GCP Storage SDK requires serde_json >= 1.0.132
- Pin ensures explicit compatibility with GCP SDK
- Version 1.0.145 satisfies the 1.0.132 constraint
