Upgrade to ioredis 6

11.0.0 (2026-09-02)

• chore!: upgrade ioredis to v6 (569893a)

Bug Fixes

• revert ioredis to v5 on the 10.x line (558fa51), closes #77

BREAKING CHANGES

• ioredis 6 uses RESP3 by default (set protocol: 2 on a
  connection to keep the v5 wire protocol), switches the default
  retryStrategy to exponential backoff with jitter, enables TCP keepAlive
  at 30s, and requires Node.js 20 or newer. Packages that consume
  ioConnection must be on the same ioredis major.
