📝 Walkthrough

Walkthrough

This PR performs a coordinated patch-version update of AWS SDK Go v2 modules. The core SDK, credentials, and multiple service modules are bumped to newer patch versions. Generated metadata constants and changelog entries are updated to reflect these releases. Auth scheme matching logic is improved across signin, sso, ssooidc, and sts services. Endpoint resolver code is refactored for smithy-go v1.26.0 compatibility.

Changes

AWS SDK Go v2 Coordinated Update

Layer / File(s)	Summary
Dependency manifest version updates go.mod, vendor/modules.txt	Core SDK and service module versions are bumped across go.mod and vendor/modules.txt: aws-sdk-go-v2 1.41.8→1.41.9, credentials 1.19.18→1.19.19, signin 1.1.0→1.1.1, sso 1.30.18→1.30.19, ssooidc 1.36.1→1.36.2, sts 1.42.2→1.42.3, and internal packages (imds, configsources, endpoints/v2, v4a, accept-encoding, presigned-url) with coordinated increments.
Generated module version constants and changelog entries vendor/github.com/aws/aws-sdk-go-v2/.../go_module_metadata.go, vendor/github.com/aws/aws-sdk-go-v2/.../CHANGELOG.md	Across all updated packages, goModuleVersion constants are bumped to match tagged releases, and new CHANGELOG.md entries document updates to smithy-go v1.26.0 and latest SDK module versions. Affected files span core AWS SDK, credentials, internal packages (imds, configsources, endpoints/v2, v4a), service-internal packages (accept-encoding, presigned-url), and services (signin, sso, ssooidc, sts).
Auth scheme ID matching improvements vendor/github.com/aws/aws-sdk-go-v2/service/{signin,sso,ssooidc,sts}/auth.go	New unexported matchSchemeID(registered, option string) bool helper function is added to each service. This function implements flexible scheme ID matching: exact equality or suffix-after-# matching. The selectScheme logic in each service is updated to use this matching instead of strict string equality, improving auth scheme resolution.
Endpoint resolver refactoring: StringSlice cleanup and scheme ID updates vendor/github.com/aws/aws-sdk-go-v2/service/{signin,sso,ssooidc,sts}/endpoints.go	Local stringSlice helper types are removed and replaced with compile-time references to rulesfn.StringSlice. In STS endpoints.go, SchemeID values in smithyauth.SetAuthOptions are changed from aws.auth#sigv4 to sigv4 across all region/partition endpoint branches, aligning with smithy-go v1.26.0 architecture changes.
