Deprecate Canton min-NOP bypass wrappers (*AllowingCantonMinNOPs)

Deprecate Canton min-NOP bypass wrappers (*AllowingCantonMinNOPs)

Problem

ccv currently wraps generic cross-family changesets with Canton-specific *AllowingCantonMinNOPs helpers (see chainlink-deployments offchain_pipelines.go). This is an antipattern — family logic should live in adapters, not wrapper changesets.

Resolution (min-NOP)

Already fixed in adapter layer: CantonChainFamilyAdapter.ValidateNOPsTopology enforces 9 (mainnet) / 4 (testnet). Generic ValidateForEnvironment delegates per family; Canton never hits EVM's 15-NOP rule.

WithCantonProductionMinNOPCheckBypassed and lane/offchain *AllowingCantonMinNOPs wrappers are legacy and can be removed for full production topologies.

Remaining gap (separate from min-NOP)

JD ListNodeChainConfigs validation in apply-executor-config. Proposed fix: RequiresNodeChainSupportInJD() bool on ExecutorConfigAdapter (chainlink-ccip); Canton adapter returns false during rollout.

Tasks

• Deprecate then remove *AllowingCantonMinNOPs in chainlink-canton
• ccv: revert generic apply-executor-config to v2_0_0.ApplyExecutorConfig(registry, chainFamilyRegistry)
• chainlink-ccip: adapter-driven JD validation skip
• Remove duplicated applyExecutorConfigSkippingChainSupportValidation
