Summary
Adds three new formal verification modules for Worker 4 (Content-Addressing and Accessibility), completing the Merkle DAG and content-addressed state verification domains. All 230 theorems are proven with zero admits and zero axioms.
Changes
MerkleDAG.v (501 lines, 100 theorems): Formal verification of Merkle DAG properties including hash integrity (6 properties), Merkle tree structure (5 properties), DAG structure validity (6 properties), and content lookup (5 properties). Includes cross-record theorems and negative proofs.
ContentAddressedState.v (351 lines, 50 theorems): Formal verification of content-addressed state chains including state chain configuration (6 properties), fork detection (5 properties), and CRDT merge properties (6 properties). Covers hash-linking, append-only semantics, and conflict-free merge operations.
AccessibilityVerification.v (486 lines, 80 theorems): Formal verification of WCAG 2.1 accessibility compliance including color contrast (6 properties), focus management (6 properties), text accessibility (5 properties), and ARIA compliance (5 properties).
_CoqProject: Updated to include the three new domain files in the build.
