feat(trust-lattice): complete Sprint 7100 VEX Trust Lattice implementation

Sprint 7100 - VEX Trust Lattice for Explainable, Replayable Decisioning Completed all 6 sprints (54 tasks): - 7100.0001.0001: Trust Vector Foundation (TrustVector P/C/R, ClaimScoreCalculator) - 7100.0001.0002: Verdict Manifest & Replay (VerdictManifest, DSSE signing) - 7100.0002.0001: Policy Gates & Merge (MinimumConfidence, SourceQuota, UnknownsBudget) - 7100.0002.0002: Source Defaults & Calibration (DefaultTrustVectors, TrustCalibrationService) - 7100.0003.0001: UI Trust Algebra Panel (Angular components with WCAG 2.1 AA accessibility) - 7100.0003.0002: Integration & Documentation (specs, schemas, E2E tests, training docs) Key deliverables: - Trust vector model with P/C/R components and configurable weights - Claim scoring: ClaimScore = BaseTrust(S) * M * F - Policy gates for minimum confidence, source quotas, reachability requirements - Verdict manifests with DSSE signing and deterministic replay - Angular Trust Algebra UI with accessibility improvements - Comprehensive E2E integration tests (9 scenarios) - Full documentation and training materials 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
