fix: prevent greetings workflow 0-job failure runs on push/synchronize events

[Copilot]

Description

greetings.yml was producing failure workflow runs with 0 jobs whenever a branch was pushed. GitHub evaluates pull_request_target workflows on push/synchronize events; since the workflow only declared types: [opened], no jobs were scheduled — and GitHub marks 0-job runs as failure.

Fix: Add an explicit if: guard to the greeting job:

jobs:
  greeting:
    if: github.event_name == 'issues' || github.event_name == 'pull_request_target'

When the job condition is false, GitHub skips it (run concludes success) instead of creating an empty run that fails. No change to functional behavior on issues: opened or pull_request_target: opened events.

The other three workflows (pr-issue-bot.yml, assign-pr-author-on-merge.yml, auto-close-mentioned-issues.yml) already have job-level if: guards and were not affected.

Summary by cubic

Prevents phantom CI failures by adding an event guard to the greetings workflow so it only runs on issues and pull_request_target. Other workflows already had proper guards, so this eliminates 0‑job failures on push/synchronize and restores green checks.
