Align TypeScript SDK Commons requests with Protocol‑Commons v1.1.0

[GsCommand]

Motivation

• The TypeScript SDK was constructing Commons requests using a nested body and x402/actor wrappers which contradict the Protocol‑Commons v1.1.0 schemas that require a flat top‑level input string shape.
• This change makes the SDK the single source of truth for request construction follow Protocol‑Commons v1.1.0 exactly while preserving response‑side compatibility only where needed.

Description

• Implemented a canonical flat request builder buildCommonsRequest() and exported CommonsRequest and verb‑specific types so request typing matches the v1.1.0 schemas exactly, and marked actor in ClientOptions as deprecated.
• Updated all Commons verb helpers to use buildCommonsRequest() and to send a flat payload { verb, version, input, mode? } instead of nested input, limits, actor, or x402 wrappers; call() now posts the canonical payload.
• Updated the CLI to accept the flat Commons input (--input) and adjusted examples/docs (README.md, typescript-sdk/README.md, EXAMPLES.md, QUICKSTART.md) to teach the flat request shape.
• Updated and added unit and smoke tests to assert the flat request structure and removed reliance on request‑side x402/actor defaults while preserving legacy response normalization (receipt envelope parsing) only.

Testing

• Ran type checking with npm run typecheck in typescript-sdk, which completed successfully.
• Ran the package tests with npm test in typescript-sdk, which ran unit and CLI smoke suites and passed (52 passed, 0 failed) and the CLI smoke tests passed.
