feat: Complete Phase 5 Framework Adapters — Hono, Express, Fastify, SvelteKit, Nuxt, Next.js Server Actions

[Copilot]

Completes all remaining Phase 5 roadmap items. The Hono adapter was a middleware-only stub; Express/Fastify were only available via NestJS; SvelteKit/Nuxt had no support.

Hono Adapter (expanded)

• createHonoApp() with full Auth/GraphQL/Meta/Data/Storage route dispatchers, AuthPlugin service support, .well-known discovery — 26 tests (up from 3)

Next.js Server Actions (new)

• createServerActions() returning typed ServerActionResult<T> with query, getById, create, update, remove, getMetadata

"use server";
const actions = createServerActions({ kernel });
const result = await actions.query('account', { limit: 10 });

New Adapter Packages

Package	Pattern	Tests
@objectstack/express	Express v5 Router ({*path} wildcards)	2
@objectstack/fastify	Fastify plugin via objectStackPlugin()	9
@objectstack/sveltekit	Web-standard Request/Response handler for +server.ts	17
@objectstack/nuxt	h3 router via createH3Router()	7

All adapters follow the established pattern: HttpDispatcher from @objectstack/runtime, AuthPlugin service preferred with dispatcher fallback, consistent error shape.

Security

• Bumped fastify peer dep to ^5.7.2 (Content-Type validation bypass fix)
• Bumped h3 peer dep to ^1.15.5 (request smuggling fix)
• CodeQL: 2 informational js/missing-rate-limiting on auth handlers — rate limiting is an app-level concern, not the adapter's

ROADMAP.md

• Phase 5 status: 🟡 → ✅, Package Status Matrix updated with new packages

Original prompt

完成roadmap开发，Phase 5: Framework Adapters (🟡 Mostly Complete)

Goal: First-class integration with popular web frameworks.
Completed

Next.js Adapter — App Router, Auth/GraphQL/Meta/Data/Storage handlers (9/10)
NestJS Adapter — Full DI module, Express/Fastify support (10/10)
Hono Server Plugin — Production HTTP server with static file serving
Remaining

Hono Adapter — Currently a stub (middleware only). Needs full route dispatchers for Auth/GraphQL/Meta/Data/Storage matching Next.js/NestJS completeness
Next.js Server Actions — Support for React Server Actions pattern
Express Adapter — Standalone Express integration (currently via NestJS only)
Fastify Adapter — Standalone Fastify integration (currently via NestJS only)
SvelteKit Adapter — Community request

Pull request overview

This PR completes Phase 5 of the ObjectStack roadmap by delivering comprehensive framework adapter support. It expands the existing Hono adapter from a middleware stub to a full-featured implementation, adds Next.js Server Actions support, and introduces four brand-new adapter packages for Express, Fastify, SvelteKit, and Nuxt. All adapters follow the established HttpDispatcher pattern with consistent AuthPlugin service integration.

Changes:

• New Packages: Added standalone adapters for Express (v5), Fastify, SvelteKit, and Nuxt with full Auth/GraphQL/Metadata/Data/Storage route dispatchers
• Hono Expansion: Expanded from middleware stub (3 tests) to full createHonoApp with all route dispatchers (26 tests)
• Next.js Server Actions: Added createServerActions() API with typed ServerActionResult for query/getById/create/update/remove/getMetadata operations
• Security: Bumped fastify to ^5.7.2 and h3 to ^1.15.5 to address CVE fixes
• ROADMAP: Updated Phase 5 status from 🟡 (Mostly Complete) to ✅ (Complete) and added 5 new packages to the Package Status Matrix
