chore(deps): bump sha2 to 0.11 and rand to 0.10

- sha2 0.10 -> 0.11 changes the digest output type so it no longer
  implements LowerHex; switch compute_hash to use the existing
  bytes_to_hex helper (same lower-hex output, byte-identical).
- rand 0.9 -> 0.10 removes rand::rng().random::<[u8; N]>(); use the
  top-level rand::random::<[u8; N]>() instead. Drops the now-unused
  use rand::Rng import.

cargo build + cargo test (30 passed) green.
