remove old SA1019 lint:ignore

[dragonsinth]

We have a global exclude on this one.

Note

Low Risk
Comment and gitignore-only cleanup with no runtime or API behavior changes.

Overview
Removes per-import //lint:ignore SA1019 comments across the library, CLI, and tests now that staticcheck already excludes SA1019 globally (inherit,-SA1019 in the Makefile). Import lines are unchanged aside from dropping those annotations; one similar ignore above proto.MessageType in format.go is removed as well.

Also adds .claude/ to .gitignore so local Claude tooling files are not tracked.

Pull request overview

This PR removes now-unnecessary //lint:ignore SA1019 annotations (previously used to silence staticcheck deprecation warnings) because SA1019 is already globally excluded in this repo’s staticcheck invocation. It also updates .gitignore to ignore local Claude tooling metadata.

Changes:

• Remove per-import //lint:ignore SA1019 comments across library code, CLI, and tests.
• Remove the remaining //lint:ignore SA1019 near proto.MessageType usage in format.go.
• Add .claude/ to .gitignore.
