perf(doi): 13x speedup for /repos/doi/summary (108s → ~6s)

Two fixes:
1. skip_consistency=True in summary mode — omits C7/C13 subprocess calls
   (consistency_check.py) which were the main bottleneck (32 spawns for 16 repos).
   Full check still available per-repo via GET /repos/{slug}/doi.
2. asyncio.gather — all repos evaluated in parallel instead of sequentially.

Also: rename Repositories page title from "Repos" to "Repositories".
