Reorganize: move Phase 2 data under phase-2-the-stack-v1/

- Prefix all existing config names with phase-2-the-stack-v1-
- Move all parquet files under data/phase-2-the-stack-v1/<config>/
- Add banner to README explaining the rename for downstream consumers
- Frees the short condition-* namespace for incoming Phase 3 builds
(The Stack v2, streamed with near-dedup)

 # Language Decoded | Multilingual Code Dataset
 
+> **Note (2026-04-21):** Phase 2 configs have been renamed to `phase-2-the-stack-v1-*` and moved under `data/phase-2-the-stack-v1/`. Existing `load_dataset(...)` calls using the short `condition-*` names will no longer resolve. The short `condition-*` namespace is reserved for Phase 3 builds (streamed from The Stack v2, coming soon). See the _Loading the Dataset_ section below for updated config names.

 Multilingual Python code datasets for the **Language Decoded** project (part of [Cohere's Tiny Aya Expedition](https://aya.for.ai)), investigating whether code's reasoning benefit for language models is **language-dependent** or **structure-dependent**.
