Fixes the two Windows pain points when routing code review to the Grok CLI
(native Windows grok.exe driven from Git Bash):
- winpath() (cygpath -w; no-op off Windows) on every path handed to grok.exe
(--prompt-file, --cwd) -> deterministic, space-safe; removes reliance on
MSYS's argv auto-conversion heuristic (the 'confounded by Windows paths').
- review mode resolves to an absolute Windows path (handles absolute/spaced paths).
- NEW review-files [-i instr] <f1> [f2...]: review a set of files together.
- NEW review-diff [-C <repo-dir>] [-i instr] <gitref> [-- <pathspec>]: review a
git diff; -C targets submodules (e.g. guru-rmm). Diff goes via --prompt-file,
not a shell arg -> no 'quote hell'.
Tested: text, review (spaced abs path), review-files (2 tray modules),
review-diff (self-review of these changes). SKILL.md updated.
