Clarify MiMo API and Token Plan access and upgrade models / 明确 MiMo 接入方式并升级模型 (#10655)

Problem: region-first filtering hid MiMo API versus Token Plan access and new connections retained the V2.5 model catalog. Root cause: product selection depended on region, MiMo lacked a one-time model migration, and floating CI Node versions made frontend artifact producers and consumers disagree. Fix: select access type before cluster and protocol, clarify independent credentials and usage, default new connections to V2.6, and atomically append models to eligible official connections without changing existing defaults or custom data. Preserve previous-writer TOML compatibility, share repeated frontend defaults within existing budgets, and pin artifact workflows to one exact Node runtime. Verification: root and Desktop suites, previous-reader migration round trips, frontend and browser regressions, unchanged production bundle budgets, cross-platform CI, race checks, Windows packaging, memory screening, CodeQL, and release-control contracts passed. All review threads were clear before merge.

 | Contract | Behavior |
 | --- | --- |
-| Saved provider TOML and credentials | Unchanged; no migration or automatic rewrite |
+| Saved provider TOML and credentials | Browsing makes no writes; the one-time MiMo model upgrade below preserves credentials and selections |
 | Existing preset IDs | Preserved |
 | Desktop `ProviderPresetView.catalog` | Additive display metadata; old clients ignore it |
 | New frontend with older host | Generated known-ID fallback; unknown presets remain individually accessible |
 | Provider request prefix | No catalog metadata is added to model requests |

+## MiMo API and Token Plan
+
+Choose **Pay-as-you-go API** or **Token Plan** first. The API uses
+`MIMO_API_KEY` and does not show a region selector. Token Plan uses
+`MIMO_TOKEN_PLAN_API_KEY` and then offers China, Singapore and Europe service
+clusters. Changing clusters preserves a selected protocol when that preset is
+available. Token Plan is restricted to supported AI coding tools; its key and
+quota are independent of the ordinary API.
+
+New connections default to `mimo-v2.6-pro`, with `mimo-v2.6-flash` also included.
+V2.5 IDs remain available for existing selections. Schema version 12 appends
+the V2.6 models once to eligible saved official V2.5 connections. It preserves
+the current default, model order, custom rates, credential references and unknown
+fields. Explicit custom request URLs and third-party endpoints are excluded.
+The model additions and version marker are written atomically under the config
+edit lock; subsequent starts do not restore models the user removes.
+
+| Field or format | Old-data behavior | New reader | Previous schema-v11 reader | Conclusion |
+| --- | --- | --- | --- | --- |
+| `models`, `default`, model references | Existing V2.5 selections remain first/default | Appends V2.6 once; keeps selections | Reads and saves model IDs without switching defaults | Compatible |
+| `config_version = 12` | Earlier versions are eligible for startup migration | Prevents repeated additions after deletion | Retains the marker when saving | Compatible |
+| `prices`, `vision_models`, unknown fields | Preserves user rates and explicit vision choices | Extends known curated vision lists and missing V2.6 prices; preserves unknown data during migration | Reads the existing fields and canonical nested price tables | No new persisted field types |
