fix: StatusDot shows 'Failed' state in red, parseRepoSlug handles SSH URLs

StatusDot: added 'failed' status with text-destructive/bg-destructive.
Previously showed failed repos as 'Pending' with pulsing dot.

parseRepoSlug: now matches both HTTPS (github.com/owner/repo) and
SSH (git@github.com:owner/repo) URL formats.

Skipped: function_count > 0 guard (intentional -- 0 before indexing is
misleading), SortTab -> shadcn Tabs (custom component is simpler).
