[RFC] RL Insight refactor directory structure

RFC: Refactor Repository Layout and Add UT Coverage

Background

RL-Insight currently has two parts:

• Online Monitor was previously under experimental/.
• Offline analysis already exists as a separate set of parser, data check, pipeline, and visualization utilities.

To make the project structure clearer, Online Monitor should become the main rl_insight/ package, while offline analysis should be released as recipe/.

Proposal

Refactor the repository into the following structure:

rl_insight/        # online monitor, migrated from experimental/
recipe/            # offline analysis
data/recipe/       # sample data for recipe
docs/monitor/
docs/recipe/
examples/monitor/
examples/recipe/
tests/monitor/
tests/recipe/

Principles

Move Online Monitor from experimental/ to rl_insight/.
Package offline analysis as recipe/.
Put recipe sample data under data/recipe/.
Split docs, examples, and tests by domain.
Use file moves when possible to preserve Git history and avoid large rewritten diffs.

UT / CI Updates

Move existing offline tests to tests/recipe/.
Update CI paths and commands for the new recipe test locations.
Ensure recipe tests use sample data from data/recipe/....
Add or expand Online Monitor CI in follow-up work.

Expected Benefit

This makes rl_insight/ the clear entry point for Online Monitor, keeps offline analysis self-contained under recipe/, and prepares the repository for better CI coverage across both domains.

Thanks for your contribution @mengchengTang ! RL-Insight is ready to move on to the next stage.

Please pay special attention to CI coverage for the online monitor — make sure CI can catch the vast majority of functional issues. Also keep generalizability in mind, so RL-Insight can be easily adapted to different RL training frameworks.
