Greptile Overview

Greptile Summary

adds pre-commit hook for ruff linter to enforce ban on isaacsim.core.utils imports via TID251 rule

• .pre-commit-config.yaml: adds ruff v0.14.3 hook with --fix and --exit-non-zero-on-fix flags
• pyproject.toml: enables TID251 (banned-api) and bans isaacsim.core.utils, .prims, and .stage submodules
• critical issue: configuration missing isaacsim.core.utils.torch, which is imported in 9 files and won't be caught by current rules

Confidence Score: 2/5

• safe to merge after adding missing isaacsim.core.utils.torch to banned-api list
• pre-commit hook is correctly configured, but banned-api rules incomplete - missing .torch submodule means 9 files importing it won't trigger the ban, defeating the PR's purpose
• pyproject.toml needs isaacsim.core.utils.torch added to banned-api config
