Summary

Implements CLI-037 with a deterministic end-to-end smoke workflow that exercises the built and linked StellarForge executable.

Included

• builds the production CLI from the committed source
• installs dependencies from the committed lockfile with lifecycle scripts disabled
• links the built package in CI and invokes stellarforge as an installed executable
• validates --help and --version
• executes stellarforge doctor with bounded subprocess diagnostics
• generates a Basic App through the linked CLI
• runs stellarforge test inside that generated project
• generates a Smart Contract project
• writes non-secret Testnet project configuration
• performs stellarforge deploy against a local fake stellar executable
• verifies the exact deployment arguments and mock contract output
• keeps live network checks and secrets out of normal PR validation

Determinism / Security

• no live Stellar network dependency
• no wallet secrets, seed phrases, API tokens, or npm publish credentials
• fake Stellar CLI exists only inside a temporary test directory
• subprocess calls use executable + argument arrays with shell: false
• deployment still passes through the production Testnet-only validation path
• external diagnostic probes are bounded by the CLI diagnostic timeout

Closes #40
