Add a skill source mode

Today the extension supports:

SyncEngine.sync branches on configService.getSourceMode():

      const skillIndex = sourceMode === "github-repo"
        ? await this.getGithubSkills()
        : await this.registryService.listSkills();

      const indexByName = new Map(skillIndex.map((skill) => [skill.name, skill]));

      for (const skillName of optedInSkills) {
        const meta = indexByName.get(skillName);
        // ...
            const content = sourceMode === "github-repo"
              ? await this.getGithubSkillContent(meta.path)
              : await this.registryService.getSkillContent(meta.path);

Checklist for a new SourceMode

1. Types — Extend SourceMode and SkillManagerState["sourceMode"] if the UI exposes the mode.

2. Settings — Add enum value + any new keys under contributes.configuration.properties in package.json (skillSync.sourceMode, plus URLs or IDs).

3. ConfigService — getSourceMode, setSourceMode, and isSourceConfigured() must know how to detect a valid configuration for the new mode.

4. Service — Implement a class (or extend an existing one) that can produce SkillMeta[] for the catalog and SkillContent (or package file fetches) compatible with SyncEngine:

   • For packages, set skillType: "skill", path to the package root identifier, and populate skillFiles with every file path the engine should download.
   • For single-file rules, use skillType: "cursor-rule" and a stable path/shaOrVersion.
