Core 0.1.0 — independent Workbench integration

Standalone core release for the Workbench repository separation.

• Keeps the ten MCP tools, forensic execution, saved-result reuse, and existing evidence/report contracts.
• Provides public integration API revision 1 and a packaged authoritative report specification.
• Moves the application to volatility-workbench; legacy module launchers give migration guidance or delegate when installed.

Verified with 91 core tests (one optional skip), an isolated wheel installation, and both supported MCP protocol modes. No real memory investigation was repeated.
