Subject: [PATCH] chore(deps): bump dev-dep bincode 2 -> bincode-next
 3.0.0-rc.13

bincode is unmaintained (RUSTSEC-2025-0141). Migrate the dev-only
round-trip test in src/gg.rs to bincode-next 3.0.0-rc.13, the fork
adopted in postguard PR #182.

- Cargo.toml: replace `bincode = "2"` with `bincode-next = "=3.0.0-rc.13"`
  pinned to block surprise rc bumps. Features narrowed to `std,serde`.
- src/gg.rs: rename `bincode::` -> `bincode_next::` in test_round.
- rust-version: 1.65 -> 1.91.1 (required by bincode-next 3.0.0-rc.13).

Refs #15.
