release: v0.9.1 — fix CI (rustls-tls, Python pin, idempotent publish)

- Switch reqwest from native-tls to rustls-tls (fixes manylinux OpenSSL build)
- Pin Windows wheels to Python 3.13 (PyO3 0.24.x max)
- Make crates.io publish idempotent (|| true per crate)
- Fix clippy warnings in optimize.rs

+### Fixed
+
+- **CI: Linux wheels** — switched `reqwest` from `native-tls` (OpenSSL) to `rustls-tls` (pure Rust); eliminates `openssl-sys` build failure in manylinux containers
+- **CI: Windows wheels** — pinned Python to 3.13 and replaced `--find-interpreter` with explicit `--interpreter python3.13`; PyO3 0.24.x does not support Python 3.14
+- **CI: crates.io publish** — made publish step idempotent (`|| true` per crate) so already-published versions don't fail the job
+- **Clippy** — fixed `needless_range_loop` and `excessive_precision` warnings in `src/optimize.rs`
