feat(self-inspect): add @devframes/self-inspect package

[antfubot]

Summary

Ports the self-inspect plugin from vite-devtools to the devframe monorepo as a first-party @devframes/self-inspect package.

What this adds

Node-side — A selfInspect() factory returns a DevframeDefinition that, when mounted via mountDevframe(), registers six RPC functions for inspecting hub state at runtime:

RPC function	What it returns
self-inspect:get-docks	All registered dock entries with metadata
self-inspect:get-rpc-functions	All registered RPC functions with type/schema/dump info
self-inspect:get-client-scripts	Client scripts attached to action/custom-render/iframe docks
self-inspect:get-shared-state-keys	All shared-state keys
self-inspect:get-auth-tokens	Trusted auth token records
self-inspect:revoke-auth-token	Revoke a trusted auth token

Client-side — A Vite + Preact SPA with five inspection tabs: RPC Functions, Docks, Client Scripts, Shared State, Auth Tokens. Connects via connectDevframe() and is served from dist/client/ at the mount path.

Usage

import { mountDevframe } from '@devframes/hub/node'
import { selfInspect } from '@devframes/self-inspect'

// In hub setup:
await mountDevframe(ctx, selfInspect(), { dock: { category: 'advanced' } })

Changes

• packages/self-inspect/ — new package (@devframes/self-inspect)
• alias.ts / tsconfig.base.json — workspace path alias for the package
• turbo.json — build task with correct dependency chain
• vitest.config.ts — registers the package as a vitest project
• tests/__snapshots__/ — API snapshot for the new package

Porting notes

The get-devtools-plugins function from the original (which lists Vite plugins by inspecting viteConfig.plugins) was intentionally omitted: it is Vite-specific and does not apply to the framework-neutral devframe context.

This PR was created with the help of an agent.
