fix(coding-agent/tools): fixed path resolution to accept bare directory names in path lists

- Fixed path resolution to accept bare directory names without trailing slashes in comma/space-separated path lists.
- Added existence check for bare path tokens before rejecting them as invalid, allowing directory names like 'packages' to be resolved correctly.
- Added test case verifying grep tool accepts bare space-separated directory names without trailing slashes.
