Add fast-CI workflows to github actions

[ostinru]

Add fast CI workflow to github actions.

This covers:

• main java code

Out of scope:

• C-lang code (it seems that it was moved to main cloudberry codebase)
• CLI golang code (it broken)

NOTES:

1. most of the linter rules disable - I don't want to fix it before cherry-picking all commits
2. it fails to run ginko tests (that I cannot reproduce locally). My plan here is to cherry-pick commits to pull codebase to up to date golang (and ginko v2).
3. I'd like to create heavy-ci workflow, where we can run automation & pg_regress tests in docker-compose. But it will take quite a lot of time to do.

Hi @ostinru thanks for your work! I tested on my branch, and it can run: https://github.com/tuhaihe/cloudberry-pxf/actions/runs/17091386265.
