chore(ci): add Gremlin Console smoke test

[contrueCT]

Purpose of the PR

• close [Improve] add macOS Apple Silicon smoke test for Gremlin Console #3015

Add a focused Gremlin Console smoke test for the server distribution entry point.

This follows up on #3015 and the review note from #3010. The existing macOS RocksDB CI covers server compile, core tests, startup, and API tests, but it does not directly exercise bin/gremlin-console.sh. This PR adds a lightweight non-interactive smoke test for that path on macOS and Linux.

Related context: #3006 reported user-facing build/startup issues and mentioned Gremlin Console behavior on Apple Silicon, but this PR only adds CI validation and does not assume a specific Jansi or Java compatibility root cause.

Main Changes

• Add run-gremlin-console-smoke-test.sh
  • Generates a tiny Groovy script
  • Runs bin/gremlin-console.sh -- -e <script>
  • Verifies the expected gremlin-console-smoke-ok marker
  • Cleans temporary script/log files with trap
• Run the smoke test in Linux Server CI only for the RocksDB matrix entry
• Run the same smoke test in macOS RocksDB CI on both Intel and Apple Silicon runners

Verifying these changes

• Trivial rework / code cleanup without any test coverage. (No Need)
• Already covered by existing tests, such as (please modify tests here).
• Need tests and can be verified as follows:
  • Ran bash -n hugegraph-server/hugegraph-dist/src/assembly/travis/run-gremlin-console-smoke-test.sh
  • Ran git diff --check

Does this PR potentially affect the following parts?

Pull request overview

Adds a lightweight CI smoke test to validate the HugeGraph server distribution’s bin/gremlin-console.sh entrypoint (non-interactive) on Linux and macOS, addressing the coverage gap called out in #3015.

Changes:

• Introduce a new Travis/CI helper script that runs Gremlin Console with a tiny Groovy script and asserts an expected marker in output.
• Run the smoke test in Linux Server CI only for the rocksdb matrix entry.
• Run the same smoke test in the macOS RocksDB CI job (both Intel and Apple Silicon runners).
