The public macro name was the last product-scoped 'fai' identifier
in the SDK surface. #[chain_module] is now the primary attribute
(README + examples updated); #[fai_module] stays as a delegating
alias so modules written before the rename keep compiling. 0.2.1.

Brings the module SDK to WIT 1.1 in lockstep with the platform and
exposes the new host.emit-event as an ergonomic ctx.emit(name,
payload). Modules emit ephemeral progress/stream events (progress,
token streaming) delivered live to a following client and never
persisted.
- wit/world.wit → 1.1.0 (host.emit-event + use types.{payload}).
- host.rs: an emit hook (thread-local fn pointer; guest is
single-threaded). The #[fai_module] expansion installs a closure
reaching the real WIT emit-event import at the start of each
invocation; Context::emit calls through it. Outside a hub (unit
tests) it is a silent no-op.
- examples/progress: reference module emitting progress + token events;
builds clean for wasm32-wasip2, proving the ergonomics end-to-end.
The SDK keeps shielding module authors: emit is the whole surface, no
wit_bindgen in sight.
