Accepted algorithms

Omitted and empty mean different things, deliberately. Omitting it (or passing undefined) accepts all of HASH_ALGORITHMS - the backward-compatible reading for a CryptoPlugin written before algorithms existed, which supports the full set by definition. An explicit [] declares support for nothing and rejects every algorithm; it must never fall back to the full set, or a plugin could not express that.

Intersected with HASH_ALGORITHMS, so this can only ever narrow the allowlist - a crypto plugin cannot widen the library's supported set.
