fix(codegen): handle git worktrees correctly when detecting git roots

[thehowl]

Updated git root detection logic in two locations to properly handle git worktrees by using git rev-parse --show-toplevel as the primary method, with a fallback to the existing directory walking approach.

Key Changes

• misc/genstd/util.go: Modified findDirs() to first attempt git rev-parse --show-toplevel before falling back to walking up parent directories looking for .git
  • Properly calculates relative path based on the git root returned by the command
  • Normalizes path separators to forward slashes for consistency
• gnovm/pkg/gnolang/internal/softfloat/gen/main.go: Modified gitRoot() to use the same git rev-parse --show-toplevel approach with fallback to the original directory walking logic

Implementation Details

• git rev-parse --show-toplevel correctly resolves the actual git repository root even when working in a git worktree, whereas walking up directories from the current working directory may not
• Both implementations maintain backward compatibility by falling back to the original directory-walking approach if the git command fails
• The fallback ensures the code continues to work in environments where git may not be available or in non-git directories

---

This was an attempt to using claude code on web; but while good it seems to me it does too much of a self-promotion on itself (placing the session link in all of the commits). Still, the change is good and will help anyone who wants to use these in worktrees, considering also that they're becoming more ubiquitous with coding agents.
