 Roadmap item #30: docs nav with on-site sessions browser. Adds a left-side flyout nav on `/docs/*` and three new public surfaces — `/docs/sessions/about` (renders the session-history README), `/docs/sessions/<NNNN>` (per-session index), `/docs/sessions/<NNNN>/<filename>` (per-transcript view). Backend mediates the fetch from `wiggleverse/ohm-session-history` over gitea raw URLs with a small in-process TTL cache (60 s manifest, 5 min content; both env-tunable). Existing `/docs` content moves to `/docs/user-guide`; bare `/docs` redirects.
