Private repositories of a personal-account owner never appear, even with that owner's token set #465

What's wrong

SyncGitHubRepoInfoForOwner (ProjectDirector/ProjectDirector.cs:1006-1011) lists an owner's repositories with GitHubClient.Repository.GetAllForUser(owner), i.e. GET /users/{owner}/repos. GitHub documents that endpoint as returning public repositories only, even when the request is authenticated as that same user. Only Organization owners get the additional GetAllForOrg call, which does return private repos the token can see.

So the per-owner token (Set GitHub Owner Token, credential selection at ProjectDirector.cs:1226-1236 / 314-328) only helps organizations; for a User owner it changes nothing about what gets listed.

Failure scenario

1. Add owner alice (a User account) and set alice's PAT via "Set GitHub Owner Token".
2. Scan > GitHub Owners.
3. Only alice's public repositories are listed; her private ones never show up, so they cannot be cloned, compared, or used as propagation targets from the app.

Suggested fix

• Resolve the authenticated login (GitHubClient.User.Current()). When the owner is a User and equals that login (case-insensitive), list with GitHubClient.Repository.GetAllForCurrent(new RepositoryRequest { Affiliation = RepositoryAffiliation.Owner }).
• Keep GetAllForUser for other users (where public-only is correct).
• Natural to land alongside the async/exception-handling cleanup tracked in Scanning or adding a GitHub owner crashes on a 404/401/rate limit instead of skipping the owner #444, but independent of it.
