docs: add Suno Seedance HappyHorse GPT Image and Nano Banana guides

[acedatacloud-dev]

Adds five individually titled MCP/Agent Plugin guides and discovery cards: Suno, Seedance, HappyHorse, GPT Image and Nano Banana by Ace Data Cloud. Names start with the services users search for, while the introduction makes clear these are independent Ace-provided integrations, not service-brand or LibreChat-maintainer official plugins.

Guides explain the current experimental Agent Plugins operator-install path, per-instance discovery, account register/sign-in/General application, OAuth and separate personal Token routes, service access/price/balance, same-ID asynchronous results and errors. They reuse real redacted Ace Console screenshots plus an existing official LibreChat settings screenshot (v0.8.2, explicitly labeled as a reference, not an Ace run). No fabricated success media or installation claim.

Package source: AceDataCloud/LibreChatPlugins#1 is now MERGED. Public release v0.1.0: https://github.com/AceDataCloud/LibreChatPlugins/releases/tag/v0.1.0 . The five independent ZIPs include license/attribution, English/Chinese guides and screenshots, plus SHA256SUMS; every public asset was downloaded and checked after publication. Commands now use the release/tag rather than the former review branch. The packages reuse five existing MCP implementations; no hook, shared credential, billing/fallback changes or duplicated generation code. Model provider collection is separately proposed in LibreChat-AI/librechat-config-yaml#94 .

Validation on the final changed docs:

• MDX compile for five guides and Prettier check: passed.
• pnpm typecheck, pnpm lint, pnpm check:config-version: passed.
• pnpm test: 421 passed / 37 files.
• Initial pnpm build: success, 4,131 static pages. After correcting only the source-guide links to the actual review branch, final typecheck/lint/format still pass, but the repeat full build timed out exporting the unchanged / homepage after three 60-second attempts (4,085/4,131 pages generated). This final build is not claimed successful. No preview server/browser was opened.
• Package native manifest/MCP parser: 5/5; install tests: 2 passed (tracked in source PR).

Acceptance is requested as official searchable documentation. No global plugin marketplace or default provider integration is claimed; actual host OAuth/install/generation and unique billing remain separate. All four UTM fields on account/pricing links only identify the integration source; no attribution-conversion claim.

Adversarial review not requested. No merge, production deployment or new paid model/media request performed.

2026-10-19 published artifact update

Own source PR #1 merged at 5395321770f06982bfcadbabdcefbb57ff007d89. Version v0.1.0 published with five service archives and SHA256SUMS. Every asset was downloaded from its public URL; hashes match, each archive has one plugin root with 14 files, complete local EN/ZH/graphics links and license/attribution. Four focused installer/archive tests and five native parser/schema checks passed at the reviewed source head; exact-head CI passed before merge.

This update changes only the five guides' source/release references and installation text. MDX compile and whitespace check pass; no full-site test/build rerun for a link/text-only change. Earlier homepage timeout and external Actions/Vercel permissions remain separately documented. Actual LibreChat instance OAuth/host calls and official acceptance are still pending; public source/release is not claimed as global marketplace/default integration.
