WebSub / PubSubHubbub:
- Hub now accepts both /rss/:id and /atom/:id topic URLs
- WebSubSubscription stores format ("rss" | "atom")
- notifySubscribers sends RSS or Atom XML with correct Content-Type
- verifyAndStoreSubscription sends correct topic URL per format
- CI paths-ignore docs/** to skip deploy on docs-only changes
HTML processing (linkedom + escape-html):
- New html-processor.ts: body extraction, script/iframe/object removal,
event handler + javascript: URL stripping, mso-* style cleanup,
plain text → <pre> with HTML escaping via escape-html
- feed-generator.ts and entries.ts use processEmailContent
Admin UI:
- W3C validation badges (Atom + RSS) on feed detail page

- Add KV feed existence check in hub.ts to prevent SSRF via non-existent feeds (returns 404)
- Treat empty string hub.secret as absent (|| instead of ??)
- Remove misleading hub Link header from atom.ts (hub only supports RSS topics)
- Simplify double-layered hub router in index.ts (direct app.route instead of nested Hono)
- Update hub.test.ts to seed KV with feed config for tests requiring valid subscribe/unsubscribe

Add comprehensive tests for POST /hub validation (missing fields, unknown mode, non-HTTPS callback, invalid URL, wrong domain, secret > 200 bytes) and happy-path subscribe/unsubscribe (202). Also fix hub.ts to use a waitUntilSafe wrapper so executionCtx.waitUntil doesn't throw in Node test environments.
