fix: quick-open file search returns no results (#213)

The ripgrep command used --hidden with positive re-inclusion globs
('.github', '.github/**') to keep .github files visible.  However,
positive globs in ripgrep act as a whitelist — once present, only files
matching those positive patterns are returned, which excluded every
non-dotfile (including CLAUDE.md and all source files).

Drop --hidden entirely so rg uses its default behavior: skip hidden
dirs, respect .gitignore, and return all normal files.
