SCPN Fusion Core v3.4.0 — Unified CLI + Release Surface Hardening

v3.4.0 — Unified CLI Launcher + Release Surface Hardening

Highlights

• Unified CLI launcher: Replaced legacy os.system launcher with structured click CLI (scpn-fusion). Single-command suite execution via scpn-fusion all --surrogate --experimental.
• Compatibility wrapper: run_fusion_suite.py preserved as forwarding wrapper to new CLI.
• Release metadata alignment: Version bumped to 3.4.0 across pyproject.toml, setup.py, src/scpn_fusion/__init__.py, and CITATION.cff.
• CI improvements: Coverage upload lane added. README badges and quickstart docs updated.
• Streamlit demo runbook: New docs/STREAMLIT_DEMO_PLAYBOOK.md for guided dashboard walkthrough.
• Type-checking clarification: Wording changed from "strict" to "mypy gate" where configured.
