Replace all exec.Command("gh", ...) calls with the existing pkg/forge
wrapper around the Forgejo Go SDK. BugSETI no longer requires the gh
CLI to be installed.
Changes:
- fetcher: use forge.ListIssues/GetIssue instead of gh issue list/view
- submit: use forge.ForkRepo/CreatePullRequest instead of gh pr create
- seeder: use git clone with forge URL + token auth instead of gh clone
- ghcheck: CheckForge() returns *forge.Client via forge.NewFromConfig()
- config: add ForgeURL/ForgeToken fields (GitHubToken kept for migration)
- pkg/forge: add Token(), GetCurrentUser(), ForkRepo(), CreatePullRequest(),
ListIssueComments(), and label filtering to ListIssuesOpts
