fix(types): export ScanStreamOptions, RedisStatus and ClusterStatus

[milcho0604]

Three types that describe the public API are not exported, so consumers can't name them and end up re-deriving them with Parameters<...> / ReturnType<...> or widening to something looser.

type	where it shows up in the public API
ScanStreamOptions	the options parameter of scanStream(), sscanStream(), hscanStream(), zscanStream() and their Buffer variants — 14 public methods across Redis and Cluster
RedisStatus	the type of the public status property, and of the event names accepted by the on() / once() overloads
ClusterStatus	the type of Cluster's public status property

ScanStreamOptions was already exported from lib/types.ts and only needed re-exporting from lib/index.ts; the other two gain an export keyword. No runtime code is touched.

Not included: FlushQueueOptions is in the same situation but only appears in private flushQueue() and an internal DataHandledable method, so it doesn't look like public API.

Tests

test/typing/exports.test-d.ts imports the three names and checks them against the signatures they describe, so the exports can't be dropped or drift from their use sites without tsd failing. Verified by mutation:

• removing the three re-export lines from lib/index.ts → tsd fails with 5 errors (has no exported member ... ×3, plus two "Parameter type X is not identical to argument type X");
• removing only the export keyword from type RedisStatus → build fails with lib/index.ts(70,15): error TS2614;
• restored → clean.

Verification

• npm run test:tsd — passes.
• npm run lint — rc=0, same 23 warnings as baseline, none in changed lines.
• prettier --check — same 13 warnings as baseline; lib/cluster/index.ts is flagged on baseline too and the edited region is byte-identical to prettier's output.
• npm run test:js against docker:setup (single + cluster, both healthy) — 2545 passing, 34 pending, 6 failing. The six are georadiusbymember / georadiusbymember_ro ("returns the anchor member within a zero radius", RESP2/legacy + RESP3/legacy + RESP3/resp3). They reproduce identically on unmodified main with this change stashed, so they're pre-existing and unrelated to this PR.

Related: #1880 asked for RedisStatus to be exported; it was closed automatically as stale, with no maintainer decision on it.

Note

Low Risk
Type-only surface area with no runtime changes; risk is limited to accidental export removal or type drift, which tsd guards against.

Overview
Exports three public API types so TypeScript consumers can import them by name instead of using Parameters<...> / ReturnType<...>.

ScanStreamOptions is re-exported from the package entry (lib/index.ts); it already existed in lib/types.ts. RedisStatus and ClusterStatus are now exported from their defining modules (lib/Redis.ts, lib/cluster/index.ts) and re-exported from lib/index.ts. No runtime behavior changes.

Adds test/typing/exports.test-d.ts with tsd checks that these exports stay aligned with scanStream options, Redis.status, and Cluster.status.
