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.

24-25: 🗄️ Data Integrity & Integration

Confirm the TARGET_REPO dispatch contract.

TARGET_REPO comes from SYNC_TARGET_REPO, so the downstream repository is not identifiable here. Confirm that it handles repository_dispatch events with type upstream-push and reads github.event.client_payload.sha.

📝 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.

Merge Risk: 🔵 Low · up to 68859

The new workflow can fail when notification secrets are unavailable and may hold a runner indefinitely if the downstream request stalls. The PR is mergeable with explicit owner awareness or follow-up on these bounded workflow reliability risks.

- 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.
