Ripgrep's --glob flag silently returns zero results when the search target
is an absolute path and the pattern contains directory prefixes (e.g.
'apps/backend/**/*.ts' with '/project'). This is a known ripgrep behavior
where glob matching fails against paths rooted at absolute arguments.
Fix by running ripgrep with cwd set to the search path and '.' as the
search target, matching how the find backend already operates. Ripgrep
then sees relative paths internally, so directory-prefixed globs match
correctly. Output paths are resolved back to absolute via resolve().
