Teknium b7b3294c4a fix(skills): preserve trust for skills-sh identifiers + reduce resolution churn (#3251)
* fix(skills): reduce skills.sh resolution churn and preserve trust for wrapped identifiers

- Accept common skills.sh prefix typos (skils-sh/, skils.sh/)
- Strip skills-sh/ prefix in _resolve_trust_level() so trusted repos
  stay trusted when installed through skills.sh
- Use resolved identifier (from bundle/meta) for scan_skill source
- Prefer tree search before root scan in _discover_identifier()
- Add _resolve_github_meta() consolidation for inspect flow

Cherry-picked from PR #3001 by kshitijk4poor.

* fix: restore candidate loop in SkillsShSource.fetch() for consistency

The cherry-picked PR only tried the first candidate identifier in
fetch() while inspect() (via _resolve_github_meta) tried all four.
This meant skills at repo/skills/path would be found by inspect but
missed by fetch, forcing it through the heavier _discover_identifier
flow. Restore the candidate loop so both paths behave identically.

Updated the test assertion to match.
