fix: config.ts reads infrastructure.weth but no tooling generates it (#611)

Add infrastructure.weth to deployments-local.json output in both
bootstrap-common.sh (write_deployments_json) and bootstrap-light.sh,
so non-Base local forks get the correct WETH address from the
deployment file instead of silently falling back to the Base hardcode.
