Skills with the same name but different namespaces (e.g.
skills/kynan/commit and skills/will/commit) were being collapsed
into a single search result because extractSkillName discarded the
namespace. This also caused deduplicateByName to cap results
across different namespaces as if they were the same skill.
Changes:
- Add MatchSkillPath to discovery package returning both name and
namespace (the existing MatchesSkillPath is kept for compat)
- Add Namespace field to skillResult in search
- Fix deduplicateResults to use repo/namespace/name as the dedup key
- Fix deduplicateByName to cap by namespace-qualified name
- Update table, prompt, and JSON output to show qualified names
- Use skill path for install subprocess when namespace is present,
ensuring unambiguous install of namespaced skills
- Add namespace to --json fields and relevance scoring/filtering
- Add unit tests for namespace dedup, qualified names, and filtering
- Add acceptance test for namespaced skill search and install
