Pull request overview

Risk Rating: LOW

Updates CCIP deployment logic to treat USDCTokenPoolProxy as version 2.0.0 (instead of 1.7.0) across shared version constants, on-chain state loading, and candidate changeset validation/tests.

Changes:

• Replace deployment.Version1_7_0 with deployment.Version2_0_0 and introduce the 2.0.0 semver constant.
• Update CCIP token pool version allowlist and on-chain stateview switch cases for USDCTokenPoolProxy.
• Update v1_6 candidate changeset logic and tests to read/write datastore refs using 2.0.0.

File	Description
deployment/version.go	Replaces the previously referenced 1.7.0 constant with 2.0.0.
deployment/ccip/shared/token_pools.go	Updates the supported token pool version set to include 2.0.0.
deployment/ccip/shared/stateview/state.go	Loads USDCTokenPoolProxy state using type+version 2.0.0.
deployment/ccip/changeset/v1_6/cs_ccip_home.go	Updates candidate changeset validation/datastore lookup to use 2.0.0 for USDCTokenPoolProxy.
deployment/ccip/changeset/v1_6/cs_ccip_home_test.go	Updates assertions and datastore refs to use 2.0.0.

Scrupulous human review areas:

• Confirm the on-chain TypeAndVersion() returned by USDCTokenPoolProxy deployments is expected to be USDCTokenPoolProxy 2.0.0 (so stateview.LoadChainState will correctly classify the contract).
