…e JS tooling The snapshot-to-proofs generator becomes a cargo example (`cargo run --example generate_merkle_tree`) with serde/serde_json as dev-dependencies, producing the same JSON output as the TypeScript version. The anchor example no longer carries a package.json, lockfile, pnpm overrides or tsconfig, matching the Rust-only anchor test stack.

The merkle-tree-token-claimer was the last anchor example with a
package.json, kept only for its snapshot-to-proofs generator. AGENTS.md says anchor examples are Rust-only, so the generator moves to Rust.Changes
programs/merkle-tree-token-claimer/examples/generate_merkle_tree.rs: reads a snapshot JSON, skips invalid entries with a warning (bad address, non-u64 amount), builds the zero-hash-padded SHA-256 tree and writes the root plus a proof per claimant.serdeandserde_jsonare added as dev-dependencies.scripts/sample-snapshot.jsonmoves next to the example.scripts/generate-merkle-tree.ts,scripts/merkle.ts,package.json(with the leftover mocha/chai/litesvm deps),pnpm-lock.yaml,pnpm-workspace.yaml(overrides) andtsconfig.json.Testing
cargo run --example generate_merkle_tree -- examples/sample-snapshot.json out.jsonproduces JSON identical to the old TypeScript generator's on the sample snapshot.cargo fmt --checkclean;cargo clippy --example generate_merkle_treereports nothing for the example (the lib's two existingmanual_is_multiple_ofwarnings are untouched).AI disclosure
