feat(coverage): /api/ideas/stats + accept-rate line on /coverage.html

Sanity-check the idea-loop debate panel: are we accepting too generously
(>50% rate) or too harshly (<5%)? Current 7/55 = 12.7% sits in the
healthy zone.

Routes:
  GET /api/ideas/stats   {accepted, rejected, accept_rate, accepted_by_type{},
                          rejected_by_type{}}. Reads both jsonl files in the
                          idea-loop data dir; 60s cache.

UI:
  /coverage.html idea section   monospace stats line above the score-sorted
                                feed: "N accepted · M rejected · P%
                                accept rate · by type: …"
