Retire dedicated dedup Jepsen workflow

[bootjp]

Summary

• Remove the dedicated scheduled dedup Jepsen workflow.
• Let the standard scheduled Jepsen workflow exercise the default Redis/DynamoDB dedup-on path by dropping the explicit opt-out env vars.
• Update design docs to record the post-flip CI cleanup.

Validation

• actionlint .github/workflows/jepsen-test-scheduled.yml
• git diff --check
• Confirmed .github/workflows no longer references the dedup opt-out env vars or the deleted workflow.

Summary by CodeRabbit

• Chores
  • Simplified scheduled Jepsen testing by removing a retired dedicated dedup-mode job.
  • Updated the remaining scheduled test to use the default dedup behavior instead of forcing an override.
• Documentation
  • Aligned design docs with the new scheduled test coverage and rollout status.

Jepsen dedup workflow retirement

Scheduled workflow baseline .github/workflows/jepsen-test-scheduled.yml, docs/design/2026_05_21_proposed_txn_secondary_idempotency.md	Removes the explicit ELASTICKV_*_ONEPHASE_DEDUP=0 settings from the scheduled Jepsen workflow and updates the secondary idempotency doc to reference the general scheduled workflow for dedup-mode coverage.
DynamoDB rollout notes docs/design/2026_06_03_partial_dynamodb_onephase_dedup.md	Updates the DynamoDB rollout validation and decision log to describe default-on dedup coverage in the scheduled workflow and the removal of the dedicated dedup workflow.
Redis rollout notes docs/design/2026_06_10_proposed_redis_onephase_dedup_default_on.md	Updates the Redis default-on narrative, control-workflow discussion, cleanup note, and rollout instructions to match the retired dedicated dedup workflow and the remaining scheduled workflow path.

Poem

I twitched my nose at cron-time light,
then tucked the old dedup flags out of sight.
One schedule hums, the docs agree,
and carrots bloom in CI.

Code Review

This pull request updates several design documents to reflect the post-flip CI cleanup. Specifically, it documents the retirement of the dedicated dedup-mode Jepsen workflows and the removal of the legacy-path opt-out environment variables from the general scheduled Jepsen workflow, which now covers the default dedup-on path. There are no review comments, so I have no feedback to provide.
