chore: finish fai->chain naming in README, repository URL, macro internals

README still documented the crate as fai-module-sdk with a
fai_module_sdk::prelude import; the workspace repository field
pointed at the pre-rename module-sdk-rust URL; the #[fai_module]
expansion used a __fai_module_sdk_internal hygiene module. All
three now carry the chain-module-sdk name. Also note the WIT
contract is chain:platform@1.1 (additive emit-event on the
frozen 1.0 base) and document ctx.emit in the surface table.
