docs: remove import order rules enforced by cargo fmt

Import ordering is already enforced automatically by cargo fmt,
so documenting it separately is redundant and risks going stale.

 ### Import Organization
 
-Prefer **merged imports** — combine multiple items from the same crate or module into a single `use` statement with braces rather than separate `use` lines.
-
-Imports are grouped in this order, separated by blank lines:
-
-1. `use super::...` or `use crate::...` (internal)
-2. All other imports — external crates and `std::` together, sorted alphabetically
-
-`cargo fmt` enforces alphabetical ordering across external and `std` imports (it does not distinguish between them). Platform-specific imports (`#[cfg(unix)]`) go in a separate block after the main imports.
