docs(readme): sync PR #2426 managed-backend clarifications to all lan…

[JAYcodr]

Summary

• Synchronize PR docs: clarify managed backend defaults #2426 (docs: clarify managed backend defaults) changes across all four root-level README language variants (zh-CN, de, ko, ja-JP).
• The English README was updated to clarify the local-vs-managed boundary; non-English readers deserve the same disclosure.

What changed

1. Tagline (all 4 languages)

Updated the one-liner under the logo to match the new English phrasing that replaces "Private/Simple/Powerful" with an explicit "local memory + managed services" framing.

Language	Before	After
zh-CN	私密、简洁、极其强大	本地记忆，按需托管服务，简洁而强大
de	Privat, schlicht und extrem mächtig	Lokaler Speicher, verwaltete Dienste wo nötig, schlicht und mächtig
ko	프라이빗하고, 단순하며, 매우 강력합니다	로컬 메모리, 필요한 경우 관리형 서비스, 단순하고 강력합니다
ja-JP	プライベートで、シンプルで、非常に強力	ローカルメモリ、必要に応じてマネージドサービス、シンプルで強力

2. Added the "Local + managed services, upfront" warning block (all 4 languages)

This is the most important addition from #2426 — a plain-language notice that:

• local data (Memory Tree, vault, workspace, runtime) stays on-device
• sign-in, model routing, search proxying, and managed OAuth still go through OpenHuman-hosted services
• custom/local settings are available for BYOK / self-hosted paths

3. Added the managed-integration paragraph (all 4 languages)

Where the English README now has a standalone paragraph explaining that OAuth handshakes and tool calls are proxied through the managed backend by default, with an opt-in direct-mode path — this paragraph was missing entirely from all translated READMEs. Added it.

4. Updated model-routing copy (all 4 languages)

Changed from "sends each task to the right LLM under one subscription" to explicitly state that model routing uses the OpenHuman backend by default to select and proxy the right LLM.

📝 Walkthrough

Walkthrough

Four localized README files are updated to clarify OpenHuman's local-first + managed-services architecture. Hero taglines are reframed to emphasize local memory with on-demand managed services. New sections explain what runs locally (Memory Tree, workspace config) versus what uses the managed backend (login, model routing, search proxying, Composio integration). Feature descriptions are revised to detail Composio connector proxying, direct-mode configuration, and backend-driven model routing.

Changes

Localized README architecture messaging

Layer / File(s)	Summary
Hero tagline and positioning updates README.de.md, README.ja-JP.md, README.ko.md, README.zh-CN.md	Top-level tagline reframed across all four language READMEs from general privacy/simplicity emphasis to specific "local memory + on-demand managed services" positioning.
Local + managed services architecture explanation README.de.md, README.ja-JP.md, README.ko.md, README.zh-CN.md	New explanatory paragraphs added to each localization detailing the component split: locally-stored Memory Tree, Obsidian-style vault, workspace configuration, and runtime state versus managed backend handling of login, model routing, web-search proxying, Composio OAuth/integration flows, and hosted-only features.
Composio and model routing feature clarifications README.de.md, README.ja-JP.md, README.ko.md, README.zh-CN.md	Feature bullets updated across all files to specify Composio connector proxying behavior via hosted backend, direct-mode setup with user-provided API key and self-hosted webhooks, and backend-based model routing per workload with subscription coverage clarification.

Poem

🐰 Four languages, one message clear,
Local memory, managed just near,
Composio calls through the backend gate,
Direct mode waits if you customize fate.
OpenHuman's promise: simple, yet strong! ✨
