* feat(lark): serve Feishu and Lark from one deployment, per installation
The Lark integration was locked to a single open-platform host chosen
deployment-wide (MULTICA_LARK_HTTP_BASE_URL / _CALLBACK_BASE_URL,
defaulting to open.feishu.cn), so one deployment could talk to only the
mainland Feishu cloud OR Lark international — never both. Teams on the
other tenant could not use the integration at all.
Make the host per-installation. The device-flow installer already
auto-detects the tenant (Lark emits tenant_brand="lark" mid-poll); we now
persist that as lark_installation.region, carry it on
InstallationCredentials.Region, and resolve the open-platform host per
call (REST + WS bootstrap) from the region. An explicit cfg.BaseURL
(env / httptest) still overrides every region, so existing tests and
staging/proxy setups keep working.
- migration 116: lark_installation.region TEXT NOT NULL DEFAULT 'feishu'
CHECK (region IN ('feishu','lark')) — existing rows are all mainland.
- lark.Region enum + OpenPlatformBaseURL/RegionOrDefault helpers.
- registration: thread the detected region into finishSuccess so the
install-time GetBotInfo hits the right cloud AND the row records it.
- every credential-build site (patcher, replier, WS provider, union_id
backfill) copies region off the installation row.
- region is part of the WS supervisor fingerprint so a re-install that
switches cloud restarts the connection.
- API: surface region on the installation listing DTO.

* feat(lark): surface installation region in settings UI
Read the per-installation region off the listings response: build the
"Manage in Lark" dev-console host from it (open.feishu.cn vs
open.larksuite.com instead of a hardcoded mainland host) and render a
Feishu / Lark badge on each connected bot. The field is optional and
defaults to Feishu when an older server omits it (API-compat). Adds the
region_feishu / region_lark labels to all four locales.

* docs(lark): document simultaneous Feishu + Lark support
The cloud each bot belongs to is now auto-detected at install and stored
per installation, so one deployment serves both. Replace the old
"point MULTICA_LARK_HTTP_BASE_URL at larksuite for international tenants"
guidance (now just an optional override) in all four locales.

* fix(lark): repair legacy Lark-international installs on upgrade
Review follow-up (MUL-3083). Migration 116 backfilled every existing
lark_installation to region='feishu', assuming all historical rows were
mainland. But self-host deployments could already run Lark international
via the deployment-wide MULTICA_LARK_HTTP_BASE_URL override, so those
rows are really Lark — clearing the override after upgrade (which the new
docs invite) would route them to open.feishu.cn and break them.
Add a one-shot startup repair, BackfillRegionFromLegacyOverride, fired
off the hot path like BackfillBotUnionIDs: when the deployment's global
base-URL override targets open.larksuite.com, relabel the still-default
'feishu' rows to 'lark'. Gating on the deployment-wide override is what
makes it safe — every pre-existing install on such a deployment was Lark.
Idempotent; no-op on mainland / fresh deployments. Verified end-to-end
against a scratch DB (flip then 0-row idempotent re-run).
Also document that a Lark/飞书 app_id is globally unique across both
clouds, which is what makes the app_id-keyed token cache and the
UNIQUE(app_id) constraint safe across regions (review nit).

* docs(lark): fix ops guidance to match auto per-installation region
Review follow-up (MUL-3083). .env.example and docker-compose.selfhost.yml
still told operators that international Lark requires pointing both base
URLs at open.larksuite.com — now wrong, and it would push a fresh
deployment back into a single-cloud override. Rewrite them: the base
URLs are optional deployment-wide overrides; normal dual-cloud operation
keeps them empty. Document the first-boot auto-relabel for deployments
migrating off the old single-cloud override, across the integration docs
(en/zh/ja/ko).
