The RSS/Atom/JSON self link was derived from the request origin, leaking
the workers.dev host when reached directly instead of via the custom
domain. Use the configured-domain URL builders so self matches alternate.

Batch of four reader-facing improvements (TODO "Compat lecteurs + dedup"):
- JSON Feed at /json/:feedId (feed lib .json1()); all formats cross-link
- OPML export at /admin/opml (admin-protected; the registry lists every
feed URL, so it must not be public)
- Conditional GET on /rss + /atom: strong ETag + Last-Modified, 304 on
If-None-Match/If-Modified-Since, validators shared via http-cache.ts
- Duplicate-send dedup in ingestion: match by Message-ID, fall back to a
SHA-256 of normalized subject+content; a duplicate is a no-op and bumps
the new emails_deduplicated counter (status page + /api/v1/stats)
429 tests green, tsc clean, build dry-run OK. Docs (README/CLAUDE/TODO +
landing cards) updated.
