performance optimizations, read below:

- do not spawn cmd with libuv unless 'file_icons' or 'git_icons' are set
- 'path.starts_with_separator' minor regex optimization
- 'files' cmd fallback order is now fd, **rg** and then find
- 'strip_cwd_prefix' enabled again (default: 'true')
- 'cwd' header line added to 'files' and 'git' providers
