feat(sdk): rename attribute to #[chain_module], keep #[fai_module] alias
Some checks failed
CI / Linux x86_64 (Forgejo) (push) Failing after 2s

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.
