refactor: rename WIT contract fai:platform->chain:platform
Some checks failed
CI / Linux x86_64 (Forgejo) (push) Failing after 2s
Details

Tracks the platform's WIT ABI rename. The module world package is now
chain:platform@1.0.0; generated binding paths + accessor names follow.
Modules built with this SDK now import chain:platform/host. SDK crate
names stay fai-* (vendor namespace) for now.

module code keeps compiling.
