## Why
PR preview environments were broken. The dispatch half (this repo) was
fine, but the receiving `preview-env.yaml` in **ci-privileged** failed
on every run — and ci-privileged is a **private** repo, so its 5h
keepalive job bills paid Actions minutes anyway.
The intended design (started but never wired up) runs the preview env on
the **public** `twentyhq/ci-public` repo, where Actions minutes are
free, and keeps no privileged token on the runner that executes
PR-controlled code. This finishes that migration.
## What this PR does
Repoints `preview-env-dispatch.yaml` to dispatch `preview-env.yaml` on
**ci-public** instead of ci-privileged. The dispatcher app token is
simply retargeted (still `actions:write` only, via `workflow_dispatch`).
## Companion PRs (must land together)
- **twentyhq/ci-public** — converts `preview-env.yaml` to
`workflow_dispatch`; dispatches the tunnel URL back to ci-privileged for
the PR comment before any PR code runs.
- **twentyhq/ci-privileged** — adds `preview-env-comment.yaml` (posts
the PR comment with the App key) and deletes the now-dead
`preview-env.yaml`.
## Manual prerequisites (cannot be done in a PR)
- Install/authorize the `TWENTY_WORKFLOW_DISPATCHER` GitHub App on
**ci-public** with `actions:write`.
- On **ci-public**: add `vars.DOCKERHUB_RO_USERNAME`,
`secrets.DOCKERHUB_RO_TOKEN`, and `secrets.CI_PRIVILEGED_DISPATCH_TOKEN`
(fine-grained PAT, `actions:write` on ci-privileged only).
## Suggested merge order
1. ci-privileged (receiver must exist on `main` before ci-public
dispatches to it)
2. ci-public (workflow must exist on `main` before this repo dispatches
to it)
3. this PR
## Test plan
- [ ] Open an internal PR touching `packages/twenty-docker/**`; confirm
`Preview Environment Dispatch` runs and triggers `Preview Environment`
on ci-public.
- [ ] Confirm the trycloudflare URL sticky comment lands on the PR
(posted by ci-privileged's `preview-env-comment`).
- [ ] Confirm a `preview-app` label on an external contributor PR
triggers the same flow.
