feat(ai-sdk): AI SDK integration

[dinwwwh]

Summary

Brings the AI SDK integration (@orpc/ai-sdk) to v2, targeting AI SDK v7+. You can now turn procedures and contracts into AI SDK Tools:

const createTool = createToolFactory({ context: {} })
const implementTool = implementToolFactory()

const tools = {
  getWeather: createTool(getWeatherProcedure),
  createTask: implementTool(createTaskContract, { execute: ... }), // or omit execute for client-side / human-in-the-loop tools
}

• createToolFactory converts procedures into tools; implementToolFactory implements procedure contracts as tools
• aiSdkTool metadata plugin attaches base AI SDK tool options to procedures/contracts, with input/output types inferred from the contract
• Procedures with asyncIteratorObject outputs stream each event as a preliminary tool result
• Multiple input/output schemas are combined into a single schema ($defs/$ref-aware allOf composition)
• New AI SDK Integration docs page
• 100% test coverage

ℹ️ No critical issues — one minor suggestion inline.

Reviewed changes — adds the new @orpc/ai-sdk package that turns oRPC procedures and contracts into AI SDK v7+ tools, alongside an aiSdkTool metadata plugin, streaming async-iterator support, multi-schema composition, docs, and tests.

• Adds @orpc/ai-sdk package scaffold (package.json, tsconfig.json, .gitignore, README.md) following existing integration conventions.
• Adds implementToolFactory and createToolFactory for building AI SDK tools from oRPC contracts/procedures.
• Adds aiSdkTool metadata plugin so contracts/procedures can carry default AI SDK tool options.
• Adds preliminary streaming support when a procedure returns an AsyncIteratorObject.
• Adds AI SDK integration docs and updates the VitePress sidebar.
• Updates vitest.config.ts coverage excludes and refreshes pnpm-lock.yaml for AI SDK v7.

ℹ️ Nitpicks

• pnpm-lock.yaml now pulls the AI SDK v7 transitive dependency tree; no action needed beyond confirming the updated lockfile installs cleanly in CI.
