Full Spectrum Engine v1.5.0 - Enterprise Pilot Candidate

v1.5.0 adds a bounded enterprise-pilot layer while preserving the protected core.

Highlights:

• configuration/secret separation and local reference-token RBAC
• desensitization and append-only human review
• resilience primitives, structured health and metrics
• local backup/rollback and Connector output contracts
• non-author deployment walkthrough

Independent acceptance: 285 passed + 3 subtests; v1.5 black box 13/13; v1.4 regression 9/9; red-line verification 9/9; protected-core diff 0 bytes. GitHub Actions succeeded.

Boundary: controlled enterprise pilot candidate, not a production-complete platform; no automatic business execution or cross-organization network, and Connector writeback remains off by default.
