Gama_Vivian_DRP1_bulkRNAseq: v2.1.0

Patch release. No results or analysis code changed — pins are identical to v2.1.1. This release finalizes third-party reproducibility and refreshes documentation. Reproducibility Toolkit submodules pinned to the published commits and made permanently fetchable: drp1-paper-v2.1.1 tags pushed at RNAseq-toolkit 532982d and SciAgent-toolkit fb6012a (previously unreachable bare SHAs — a clean git clone --recurse-submodules now succeeds). PROVENANCE.md is the single source of truth (pins, container scdock-r-dev:v0.5.1, environment, reproduce steps). Docs Interactive dashboard link-outs → drp1.omicable.com. GitHub org rename MogilenkoLabVUMC → Mogilenko-Lab across clone URLs. Pruned stale docs: removed docs/CHANGELOG.md (superseded by tags + PROVENANCE), slimmed SETUP.md to a pointer, fixed the Historical Archive version refs (d6ec164 is v1.0, not v2.0.0), and flagged the DATA_LINEAGE artefact map as internal navigation. Sensitivity supplementary-table caption; tracked CLAUDE.md guidance.
