[codex] Build Base canary launch readiness

[FlowmemoryAI]

Summary

This PR turns the live Base canary work into a coherent launch-readiness package:

• adds committed Base canary deployment, reader checkpoint, indexer state, source-verification plan, and generated dashboard data;
• adds a dashboard /canary mode that keeps live-read canary state separate from local fixture mode;
• adds source verification automation for every canary contract, including a non-secret report file and optional bytecode checks;
• adds a dependency-light Uniswap v4-shaped afterSwap callback path with tests while preserving the boundary that this is not a production PoolManager hook deployment;
• adds V0 operator/security policy docs and updates current-state/deployment docs.

Closes #76.

Validation

• forge test
• npm test
• npm test --prefix apps/dashboard
• npm run build --prefix apps/dashboard
• npm run launch:candidate
• npm run verify:base-canary:sources -- --check-bytecode --rpc-url https://mainnet.base.org --json

Boundary

This is canary/launch-readiness work. It does not claim production L1 readiness, production Uniswap v4 hook deployment, production verifier trustlessness, token custody, dynamic fees, or AI running on-chain.
