Fixes to test client

[Roee-87]

Summary

This PR collates all of the modifications from the AMM and private mint wrapper examples. The Leo code and corresponding test files are not part of this PR (the DEX is not fully open-source), but the PRs for both of those examples are linked below:
#58
#59

packages/core/src/transports/http.ts

sendTransaction double-encoding bug — the body was wrapped in JSON.stringify() even though the caller already passes a serialized JSON string, resulting in a double-encoded payload that the node rejected. Fixed to pass the string as-is.

packages/devnode/src/index.ts

Auto-shutdown of existing devnode — added tryShutdownExisting() which sends a shutdown request to the devnode address before starting a new instance. Without this, if a test run crashed before afterAll could clean up, the next run would fail immediately with Program X already exists on the network errors.

CONSENSUS_VERSION_HEIGHTS environment variable

Set when spawning the devnode process to ensure all 14 consensus versions are correctly mapped. Without this the devnode defaults to an incorrect version schedule.

Removed createDevnodeTestClient wrapper

This was a thin convenience wrapper around createTestClient from @veil/core that unnecessarily coupled @veil/devnode to @veil/core. Call sites now construct the test client directly, which is more explicit and removes the dependency.

packages/provable/src/index.ts

Dynamic import resolution for call.dynamic — when building an execution transaction for a program that uses call.dynamic, the SDK needs the source of any dynamically-called programs pre-fetched. The previous implementation used programManager.networkClient.getProgramImports() which internally hits /latest_edition — an endpoint that returns 500 on the devnode. Replaced with direct REST fetches and regex parsing of import statements to resolve the full transitive dependency tree without touching that endpoint.

vitest.config.ts

Narrowed test glob — changed examples//*.ts to examples//*.test.ts so vitest doesn't try to execute utility and client source files as test suites.

SDK log suppression

Added an onConsoleLog filter to discard noisy SDK output during deployments (program-existence retries, snarkVM loading messages, fee authorization logs). These were obscuring actual test output without adding diagnostic value.

packages/devnode/install.sh

New install script that queries the GitHub API for the latest release, detects the host OS and architecture, downloads the appropriate zip, extracts the binary, and installs it to a configurable path (default /usr/local/bin). Supports pinning a specific version via the VERSION environment variable.

Pull request overview

This PR consolidates test-client fixes accumulated while building the AMM v3 and private mint wrapper examples (see linked PRs #58, #59). It addresses devnode lifecycle issues, an HTTP transport double-encoding bug, dynamic import resolution for call.dynamic, and adds an install script for the aleo-devnode binary.

Changes:

• Fix double JSON encoding in HTTP transport's sendTransaction, and add direct REST-based recursive import fetching in @veil/provable that avoids the broken /latest_edition endpoint on devnode.
• Make startDevnode async with auto-shutdown of any existing devnode on the same socket, set CONSENSUS_VERSION_HEIGHTS env, and add optional verbose log-to-file mode.
• Narrow vitest test glob, add @veil/leo / @veil/devnode aliases, suppress noisy SDK console output, and add a new install.sh script for installing the aleo-devnode binary.
