Replace deprecated --oracle_hash flag with the new --verifier_target flag for bb write_vk commands. This ensures the VK and Solidity verifier are generated with the correct ZK settings. - solidity-example: Use --verifier_target evm for ZK proofs - recursion: Use noir-recursive-no-zk for inner circuit, evm for outer Co-Authored-By: Claude Opus 4.5 <[email protected]>

Examples Updated
recursion/- Updated Nargo dependency, circuit code, and JS proof generationsolidity-example/- Updated package.json and proof generationweb-starter/- Updated all three bundler examples (vite, webpack, nextjs)Motivation
Fixes nightly CI failures caused by version mismatch. The CI installs nargo stable (now 1.0.0-beta.18) which requires bb 3.0.0-nightly.20260102, but the examples were pinned to older versions.
