Refactor repo structure

[zhangh43]

Task Description

This task aims to reorganize the repo topology, rename binaries/configs, and consolidate scripts into a consistent layout aligned with EloqData’s product structure.

🗂️ 1. Directory Structure
After (EloqDoc-style):

src/                → core source code (C++/storage/engine)
scripts/            → build, packaging, test utilities, including site_scons
tests/              → all test assets (unit, integration, js)
tools/              → developer tools and admin utilities
scons/            → build system modules
docs/               → developer and user docs
concourse/
etc/

Move all Python helper scripts from buildscripts/ → scripts/
Move JavaScript tests from jstests/ → tests/js/
Move Python tests from pytests/ → tests/py/
Move site_scons/ → scons/

Check and remove unused hidden file.
.pydocstyle, .pylintrc, .eslintignore etc.

⚙️ 2. Binary and Config Renaming
Rename mongod to eloqdoc, mongod.conf to eloqdoc.conf, mongo(sh) to eloqdoc-cli

🧩 3. Rename default path
For example, rename default log directories and data paths (/var/lib/mongo → /var/lib/eloqdoc).

🧪 4. Testing & Validation

Verify configuration file parsing and startup with eloqdoc.conf.

Please make sure regression ci and release ci generate the correct binary and config name.
