Pull request overview

Risk Rating: HIGH — moves Solana CCIP codec logic out of core and rewires multiple call sites to an external module (chainlink-solana), which is critical-path for message encoding/decoding.

This PR migrates Solana CCIP codec usage to github.com/smartcontractkit/chainlink-solana/pkg/solana/ccip/codec and removes the duplicated codec implementation from core/capabilities/ccip/ccipsolana.

Changes:

Replace in-repo Solana address/extra-data codec usage with chainlink-solana constructors (NewAddressCodec, NewExtraDataDecoder, etc.).
Remove the in-core Solana CCIP codec implementation and its tests (commit/execute codecs, message hasher, extra-data codec, address codec).
Update affected tests and deployment helpers to use the new codec package.

 func makeExtraArgsV2(computeUnits uint32, allowOOO bool) []byte {
-	extraArgs, err := SerializeExtraArgs(svmExtraArgsV1Tag, fee_quoter.SVMExtraArgsV1{
+	extraArgs, err := serializeExtraArgs(svmExtraArgsV1Tag, fee_quoter.SVMExtraArgsV1{
 		AllowOutOfOrderExecution: allowOOO,


svmExtraArgsV1Tag is referenced in makeExtraArgsV2, but the tag constant was removed when the in-core Solana codec was deleted (it used to live in extradatacodec.go). This test file will not compile until the tag is reintroduced (e.g., define it locally, or reference an exported tag constant from chainlink-solana/pkg/solana/ccip/codec if available).

-		ExtraDataCodec:             ExtraDataDecoder{},
+		ExtraDataCodec:             codec.NewExtraDataDecoder(),


NewGasEstimateProvider/EstimateProvider in ccipsolana still depends on helpers (parseExtraDataMap, extractDestGasAmountFromMap) that were removed along with the in-core codec (e.g., msghasher.go/executecodec.go). As-is, the ccipsolana package will not compile. Please either re-home those helpers (e.g., into ccipsolana or the new chainlink-solana/.../codec package with exported APIs) and update EstimateProvider to use them, or refactor EstimateProvider to avoid relying on the removed parsing logic.
