Complete rework of the docs site, in three passes squashed into one change:
1. P0 fact corrections across the core-loop pages (agent access model,
comment triggers and coalescing, issue lifecycle, offline/queue
semantics, task states and retries, dispatch via realtime push).
2. Chinese rewrite as the authoring language: final 12-group IA, new
"Core concepts" and "Put agents to work" pages, curated welcome page,
permanent-UI quickstart (no onboarding-wizard dependency), operator
reference restored (CLI command reference, webhook response codes,
task state/timeout tables, config set keys, upgrade notes).
3. Verification and sync: every load-bearing claim re-checked against
current main with file:line evidence (migration 103 auto-backfill,
CLI-only trigger toggling, duplication semantics, COOKIE_DOMAIN,
GitHub App variables, Qwen Code as the 17th provider); register
standards applied to all 39 pages; en/ja/ko synced from zh with
same-language heading anchors (verified, zero dead links);
17 product screenshots plus 2 diagrams wired in.
Supporting fixes: i18n middleware no longer swallows /images assets,
sidebar folder indent survives custom link padding, unused editorial
components removed.
