Pull request overview

This PR consolidates lane-connection logic across CCIP 1.6 and 2.0 by moving configuration onto the deployment/lanes ConnectChains flow, wiring EVM lane adapters into the shared registry, and removing the prior v1_7_0 “ConfigureChainsForLanes” changeset/adapter plumbing.

Changes:

• Introduces v2-oriented lane config fields in deployment/lanes and updates ConnectChains to populate/resolve them.
• Refactors EVM lane configuration sequences to ConfigureLaneLegAsSource / ConfigureLaneLegAsDest and updates related tests to use the new lanes types.
• Updates module wiring (replace directives / go.sum) to use local CCIP + CCV EVM modules consistently.

Should we remove the entire deployment/v1_7_0 folder?
