Update all classic CI workflows to use the single consolidated
pyproject.toml at classic/ instead of individual project directories.
Changes:
- classic-autogpt-ci.yml: Run from classic/, update cache key and test paths
- classic-forge-ci.yml: Run from classic/, update cache key and test paths
- classic-benchmark-ci.yml: Run from classic/, use direct-benchmark command
- classic-python-checks.yml: Simplify to single job (no matrix needed)
- classic-autogpts-ci.yml: Update to use direct-benchmark for smoke tests

Restructuring the Repo to make it clear the difference between classic autogpt and the autogpt platform:
* Move the "classic" projects `autogpt`, `forge`, `frontend`, and `benchmark` into a `classic` folder
* Also rename `autogpt` to `original_autogpt` for absolute clarity
* Rename `rnd/` to `autogpt_platform/`
* `rnd/autogpt_builder` -> `autogpt_platform/frontend`
* `rnd/autogpt_server` -> `autogpt_platform/backend`
* Adjust any paths accordingly
