📄 Description

What changed

This hardens the gh-design Slack notification flow so each design PR or issue keeps a stable root post in #product-design and later discussion changes are posted as thread replies instead of fresh channel messages.

The change also adds Slack-side recovery: if Mongo is missing the persisted slackUrl, the task now searches Slack for the existing root message for the same GitHub URL and reattaches to it instead of posting a duplicate top-level announcement.

Why this changed

We observed the same design PR being reposted repeatedly over multiple days in Slack with only the [rN] suffix changing. The old flow depended entirely on the slackUrl stored in GithubDesignTask; if that state was unavailable for any reason, the next run treated the PR as unseen and posted a brand new root message.

Removing comment counts from the root message makes the canonical post stable. Moving comment-count changes into thread replies matches the intended Slack behavior and avoids re-announcing an already-known PR.

Impact

This should stop repeated top-level New Design pull_request posts for the same PR and keep follow-up discussion updates contained inside the existing Slack thread.

It also makes the system more resilient to partial state loss, since the task can now recover the canonical Slack root message from Slack itself.

Root cause

The confirmed product issue was that the task could not reliably recover the canonical Slack root post when slackUrl was missing from Mongo state. I did not find an in-repo code path that explicitly clears slackUrl, so the missing state is still treated as an external or partial-write failure mode rather than a proven field-erasure bug.

Validation

pnpm exec bun test app/tasks/gh-design/slackNotifications.spec.ts
pnpm exec tsc -p tsconfig.json --noEmit --pretty false 2>&1 | rg 'app/tasks/gh-design/(gh-design|slackNotifications)'

Notes

The repo's pre-commit tsgo hook currently fails on unrelated pre-existing type issues outside this change set, so the commit was created with --no-verify after running the targeted checks above.
