Subject: [PATCH] chore(deps): pin rustls 0.23.45 + drop deprecated f32 import
 in vector tests

Two develop-wide red gates, one unblock PR (both verified against CI):

- RUSTSEC-2026-0285: rustls 0.23.42 in Cargo.lock trips rustsec
  audit-check on every open PR. Pin 0.23.45 (same remediation as
  gaira 2026-10-03); rustls-webpki rides along to 0.103.15. Closes #560.
- 'use std::f32;' in the vector tests module resolves f32::EPSILON to
  the deprecated module-path constant: clippy -D warnings is red on
  rustc 1.99, now including CI's stable toolchain. Removing the import
  restores the associated-constant resolution. Closes #557.

Lockfile + one test-only line; no runtime code paths touched.
