Two changes requested by the user:
1. Fold the hand-holding quickstart tutorial into README §3 (both
languages). Delete docs/quickstart.md and docs/quickstart.zh-CN.md.
Remove them from all 5 validator DOCS lists, README §6 doc index,
and charter §7 boundary table. The tutorial now lives as
README §3.0–§3.11: prerequisites, create Telegram bot, find chat id,
get JMAP credentials, run backend, sign in, fill config, register
callbacks, enable processing, verify, schedule drain, troubleshoot.
2. Replace 'gateway'/'网关' with 'load balancer'/'负载均衡器' across
all markdown (README, docs/, AGENTS.md, cloudflare-worker/README).
Also fix 4 markdown anchor links whose heading slugs changed.
Also fix charter §8 '18 safe routes' → '19' (was missed in the
earlier reference.md fix).
GATE-DOCS 6/6 PASS (71 anchors, 727 path-refs, 455 sec-refs).
Four spots told the operator to read the SPA footer to confirm a
deploy landed. The footer no longer renders a version, so restating
that would send an operator looking at a control that no longer
exists. Point them at /api/status instead; the version field itself is
unchanged.
The previous commit inserted 500+ lines into notify.rs, moving
register_push and register_telegram_webhook. Reanchor the two
deployment.md line refs; the other seven refs in that file are before
the insertion point and are unchanged.
Document the new retire-on-change contract in reference.md.
