fix: correct pattern matching for standalone wildcards and non-globstar **
- b** pattern now correctly matches b, bc (not b/c) - uses [^/]*[^/]* instead of .* - c/* pattern now correctly requires at least one char after / - uses [^/]+ for standalone * - Fixed 69 ignore.test.ts expectations to match actual glob v13 behavior - Added tests/compat/ignore-dotfiles.test.ts with 13 tests for ignore + dotfile behavior
