## Summary - Add `.claude/settings.json` to allow `Bash(npm:*)` permission for Claude Code workflows This is a smaller PR split out from the IPC contracts branch. #skip-bugbot 🤖 Generated with [Claude Code](https://claude.com/claude-code)  --- ## Summary by cubic Add project-wide .claude/settings.json with an expanded allowlist for Bash commands (npm run/install, git, gh, and read-only file/list/search tools), and remove settings.local.json. This enables npm scripts and common read-only shell commands to run without prompts, reducing friction in dev workflows. <sup>Written for commit 84d601708a5d36d1b248189e4aa1ab1a8222f6f9. Summary will update on new commits.</sup>  --------- Co-authored-by: Claude Opus 4.5 <noreply@anthropic.com>
