chore(ci): optimize rerun workflow and add macOS RocksDB coverage

[contrueCT]

Purpose of the PR

Optimize the Rerun CI workflow and add macOS coverage for the single-node RocksDB server path.

The rerun workflow now only starts the rerun decision job when an upstream CI workflow actually fails, avoiding unnecessary skipped rerun workflow records after successful or non-failure CI completions.

This PR also adds macOS RocksDB server checks in parallel with the existing Linux Server CI, covering both Intel and Apple Silicon runners for compile, core test, server startup, and API test coverage.

Main Changes

• Optimize .github/workflows/rerun-ci.yml
  • Add a job-level condition to decide-rerun-action so it only runs when github.event.workflow_run.conclusion == 'failure'
  • Remove redundant non-failure shell handling from the decision script
  • Keep the existing supported events, retry limit, delay, permissions, and gh run rerun --failed behavior unchanged
• Add macOS RocksDB coverage to .github/workflows/server-ci.yml
  • Add build-server-macos-rocksdb for macos-15-intel and macos-15
  • Run compile, RocksDB core tests, and RocksDB API tests on macOS
• Improve macOS compatibility in CI helper scripts
  • Make start-server.sh avoid Bash 4 associative arrays and use portable backend serializer selection
  • Add macOS-compatible sed -i handling
  • Make run-api-test.sh and build-report.sh resolve paths from the script/repo root and use curl/wget fallback downloads
• Stabilize Apple Silicon RocksDB API tests
  • Pass scoped SERVER_JAVA_OPTIONS for macos-15 (-Xms512m -Xmx2g) through the existing server startup -j option path
  • Keep the JaCoCo javaagent behavior intact

Verifying these changes

• Ran git diff --check

Pull request overview

This PR updates HugeGraph’s CI infrastructure for server validation. It aims to reduce unnecessary rerun handling in the GitHub Actions rerun workflow and extend HugeGraph Server CI to exercise the single-node RocksDB path on macOS, with accompanying shell-script portability fixes for BSD/macOS environments.

Changes:

• Restricts the rerun-decision job in rerun-ci.yml to failed upstream workflow runs and simplifies its decision script.
• Adds a new macOS RocksDB server matrix job in server-ci.yml for Intel and Apple Silicon runners.
• Refactors CI helper scripts to be more macOS-compatible by avoiding Bash 4-only features, handling BSD sed -i, resolving repo-root paths, and supporting curl/wget downloads.

Follow-up note for #3006: I think the Gremlin Console Apple Silicon/Jansi coverage should stay in a separate PR from this one.

This PR is scoped to rerun CI behavior plus macOS RocksDB server/API coverage. The bin/gremlin-console.sh path is a different entry point with its own Jansi/Java compatibility context, so a follow-up PR can add a focused smoke test, for example running a tiny gremlin-console.sh -- -e <script> check on macOS, and handle any related README/troubleshooting updates separately.
