Subject: [PATCH] fix(index): drop deprecated std::f32 import in vector tests

'use std::f32;' (tests module) makes bare f32::EPSILON resolve to the
deprecated module-path constant: hard clippy error on rustc 1.99
(-D warnings), blocking every pre-commit commit on current-stable
machines while CI's floating stable toolchain still passes. Removing
the import lets f32::EPSILON resolve to the associated constant
(stable since 1.43) on old and new toolchains alike.

Fixes #557
