Subject: [PATCH 1/2] chore: repo review cleanup and stabilization

- Refactored DESIGN.md and CLAUDE.md to reflect the current bash+skills architecture and remove defunct MCP server references.
- Fixed broken CI pipeline by removing non-existent package installations and stale test markers.
- Bootstrapped a functional smoke test suite in tests/ for vpstack-detect and vpstack-config.
- Updated package-lint CI job to correctly validate version synchronization.

Subject: [PATCH 2/2] chore: comprehensive repo stabilization and consistency
 update

- Expanded automated test suite with `tests/test_binaries.py` for `vpstack-b1` smoke tests.
- Replaced all stale references to `/tmp/vp_b1_run.py` with `vpstack-b1` binary across docs and skills.
- Cleaned up defunct `mcp-server` and `speechbrain_voice_anon` references in DESIGN.md, TEST-PLAN.md, and CI/CD workflows.
- Added CONTRIBUTING.md and requirements-test.txt for better developer onboarding.
- Standardized release and CI/CD workflows to focus solely on the npm-distributed package.

+# Contributing to vpstack
+
+Thank you for your interest in contributing to vpstack! This project provides research infrastructure for voice-privacy AI agents.
+
+## Architectural Principles
+
+Before you contribute, please read [DESIGN.md](DESIGN.md) and [CLAUDE.md](CLAUDE.md). The most important principles are:
+
+1.  **No Standalone Python in the Main Source**: This project uses a "Markdown Skills + Bash Binaries" model for maximum portability across AI coding agents.
+2.  **Embedded Python for Computation**: For complex algorithms (like McAdams B1), we embed Python snippets inside bash scripts in `bin/` using heredocs.
+3.  **Portability**: Skills (in `skills/`) should be pure Markdown that tells the agent what bash commands to run.
+4.  **No GPLv3 Code**: Never import or vendor code from the official VP2024 baseline. Re-implement from the published Eval Plan PDF.
+
+## How to Contribute
+
+### Adding or Updating a Binary
+- Binaries go in `bin/`.
+- They should be bash scripts that orchestrate logic or run embedded Python.
+- Always include a `--help` flag.
+- Add a corresponding smoke test in `tests/test_binaries.py`.
+
+### Adding or Updating a Skill
+- Skills go in `skills/vp-{name}/SKILL.md`.
+- Copy the preamble from an existing skill to ensure proper activation and telemetry.
+- Skills must be self-contained.
+
+### Running Tests
+We use `pytest` for automated testing.
+```bash
+pip install -r requirements-test.txt  # (or install numpy, scipy, soundfile, pytest)
+pytest -v tests/
+```
+
+## Release Process
+1. Bump the version in `VERSION`.
+2. Sync the version in `package.json`.
+3. Push a tag `v*.*.*`. The GitHub Action will handle the npm publication.

 4. **Week 1 task #2:** Write `bin/vpstack-detect` first — it's a 50-line bash script and unblocks every skill's preamble. Test on 3 voice repos and 3 non-voice repos before moving on.
