feat(hashset): make trait promotions explicit via extend

Enable `implicit_impl_as_method` (E0079) for the `hashset` package (in its
moon.pkg) and make its trait-impl promotions explicit via `extend`, in a
dedicated hashset/extends.mbt shim.

- Promote (plain `pub extend`): BitAnd (&), BitOr (|), BitXOr (^), Sub (-) -- the
  set-algebra operators -- and Default.
- Deprecate (`#deprecated(..., skip_current_package=true)` + `#doc(hidden)`):
  @quickcheck.Arbitrary, the whole Show trait (HashSet is a collection), and
  ToJson. Each message names the concrete replacement.

Also migrates hashset's blackbox test off the now-deprecated `.to_json()` on a
HashSet (-> `@json.to_json(...)`). pkg.generated.mbti gains only the promoted
HashSet operators + HashSet::default.

Part of the per-package series (see #3849 for deque). Scoped to hashset/.

Verified: `moon check --deny-warn --target all` clean; `moon test -p hashset --target all` green.

Reviewed by Codex CLI: shim covers exactly the flagged methods (Debug excluded --
existing concrete method), split matches policy, sole HashSet .to_json() caller
migrated (element calls left as trait dispatch), .mbti adds only
land/lor/lxor/sub/default, scoped to hashset/.
