fix(lint): correctly disable govet inline analyzer & deprecated gomodguard (#1574)

## Fixes Or Enhances

- Move `inline` from `linters.disable` to `settings.govet.disable` to
properly suppress Go 1.24+ false positives regarding `reflect.Ptr`
constant inlining
- Disable deprecated `gomodguard` linter to resolve golangci-lint v2
warnings
