## What
Removes the GitHub merge queue and runs what the queue used to gate —
the E2E (Playwright) suite — directly on push to `main`. If that run
fails on `main`, we ping engineering via webhook.
## Why
In the queue, only the `e2e-test` job in `ci-merge-queue.yaml` ran real
work — every other CI workflow's `merge_group` path skipped its
`changed-files-check` and tests, so the queue's status checks for those
were effectively green no-ops. The expensive thing actually gated was
E2E. Moving it to `push: main` validates the merged state post-merge
without the queue's batching overhead.
## Changes
- **Rename** `ci-merge-queue.yaml` → `ci-e2e-main.yaml` (`name: CI E2E
Main`).
- `e2e-test` now triggers on `push` to `main` (the `run-merge-queue` PR
label is kept as a manual opt-in for running E2E on a PR).
- Status-check job renamed `ci-e2e-main-status-check`.
- New `notify-main-ci-failure` job: on a failed **main push**, `POST`s
to `https://engineering.twenty.com/s/main-ci-failing` with the commit
SHA, actor, and run URL.
- **Strip dead merge-queue config** from the other CI workflows: removed
the `merge_group:` triggers and the now-unreachable `if:
github.event_name != 'merge_group'` guards from `ci-server`,
`ci-shared`, `ci-sdk`, `ci-front-component-renderer`,
`ci-test-docker-compose`, `ci-website`, and the `merge_group:` trigger
from `ci-front`, `ci-ui`, `ci-new-ui`.
## Required follow-up (not in this PR)
The merge queue itself is a **repo setting**, not code. After this
merges, disable **"Require merge queue"** on the `main` ruleset/branch
protection (Settings → Rules), otherwise GitHub keeps batching. Required
status checks tied to the old queue should also be dropped/updated.
## Behavior change
E2E now runs **after** merge rather than blocking it in the queue — a
bad change lands on `main` and then alerts (the webhook is the
mitigation), instead of being held back pre-merge.
