fix(kit): restore rpc module augmentation

[webfansplz]

Fixes #550

Restores module augmentation for custom RPC function names declared through DevToolsRpcServerFunctions.

The Kit type had become a renamed re-export of Devframe's RPC registry, while getDevToolsRpcClient() returned a client typed directly against the Devframe registry. As a result, augmenting @vitejs/devtools-kit no longer affected rpc.call().

This PR:

• restores DevToolsRpcServerFunctions as an augmentable Kit interface
• rebinds call, callEvent, and callOptional on the Kit RPC client
• keeps the runtime behavior unchanged
• adds a TypeScript regression fixture covering custom names, return types, and argument validation

The fix is intentionally scoped to Vite DevTools Kit. Devframe's native module augmentation continues to work without changes.

Pull request overview

Restores TypeScript module augmentation support for custom RPC function names in @vitejs/devtools-kit, ensuring getDevToolsRpcClient().call() is typed against the Kit’s augmentable registry rather than Devframe’s base registry (fixes #550).

Changes:

• Reintroduces an augmentable DevToolsRpcServerFunctions interface in the Kit types surface.
• Rebinds call, callEvent, and callOptional on the Kit RPC client type to use the Kit registry.
• Adds a TypeScript regression fixture/test validating custom RPC names, return typing, and argument checking.

File	Description
test/rpc-augmentation.test.ts	Adds a TS-program-based regression test to ensure Kit augmentation affects rpc.call() typing.
test/fixtures/rpc-augmentation.ts	Provides a fixture that augments DevToolsRpcServerFunctions and asserts expected type behavior.
test/snapshots/tsnapi/@vitejs/devtools-kit/client.snapshot.d.ts	Updates the public API snapshot to reflect the new DevToolsRpcClient surface and return type.
packages/kit/src/types/rpc-augments.ts	Introduces an augmentable Kit-owned DevToolsRpcServerFunctions interface extending Devframe’s registry.
packages/kit/src/types/index.ts	Exposes the new augmentation interface from the Kit types barrel and stops aliasing Devframe’s server registry.
packages/kit/src/client/index.ts	Adjusts client exports so the Kit’s RPC client types come from the Kit wrapper rather than Devframe re-exports.
packages/kit/src/client/connection.ts	Defines DevToolsRpcClient* call types bound to DevToolsRpcServerFunctions and returns DevToolsRpcClient from getDevToolsRpcClient().
