ci: add Notify on Merge dispatch workflow

[luke-mino-altherr]

What

Adds .github/workflows/notify-on-merge.yml: on every push to master, sends a repository_dispatch (event_type: upstream-push) to a downstream repository so it can react immediately instead of polling.

Follows the existing tag-dispatch-cloud.yml pattern (curl + Bearer token). Target repo and token are supplied via secrets, so nothing environment-specific lives in the file:

• SYNC_TARGET_REPO — the owner/name to notify
• SYNC_DISPATCH_TOKEN — a fine-grained token with Contents: write on that repo

Guarded with if: github.repository == 'Comfy-Org/ComfyUI' so it never runs on forks, and no-ops safely if the secrets are unset.

Warning

Review limit reached

You’ve reached a temporary PR review limit under our Fair Usage Limits Policy.

Your recent review volume is higher than typical usage, so adaptive limits are currently applied.

Next review available in: 4 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

Added a GitHub Actions workflow for Comfy-Org/ComfyUI. The workflow runs on pushes to master, validates required dispatch credentials, builds a payload with the pushed commit SHA, and sends an authenticated upstream-push repository dispatch event to a configured downstream repository.

In @.github/workflows/notify-on-merge.yml:
- Around line 20-23: Update the credential check in the notify-on-merge workflow
to log a notice and exit successfully with status 0 when DISPATCH_TOKEN or
TARGET_REPO is missing; retain non-zero exits for actual dispatch request
failures.
- Around line 26-30: Update the curl invocation in the repository dispatch step
to include finite connection and overall request timeouts, such as a 10-second
connect timeout and 60-second maximum duration. Do not add retries, preserving
the existing single repository_dispatch request behavior.

Addressed both:

1. Missing-secret handling — now logs a ::notice:: and exits 0 (soft no-op) instead of failing, so pushes to master don't red-X if a secret is ever unset. Real dispatch failures still exit non-zero (curl -f).
2. curl timeouts — added --connect-timeout 10 --max-time 60; no retries added, single repository_dispatch preserved.
