Fulfill Git Escrow

You are helping the user fulfill a git escrow bounty. This means submitting code that passes a failing test suite to claim the escrowed token reward.

There are two modes:

• Mode A (Write + Submit): You write the solution code, commit it, and submit. This is the default when no --solution-repo is provided by the user.
• Mode B (Submit Existing): The user already has a solution repo and commit. You just submit the fulfillment.

Determine the mode from the user's input:

• If they provide --solution-repo, use Mode B.
• Otherwise, use Mode A.

The escrow UID is always required.

Step 1: Check CLI availability

Run git-escrows --help to verify the CLI is installed. If it fails, try npx git-escrows --help or bunx git-escrows --help. Use whichever works for all subsequent commands. If none work, tell the user to install with npm i -g git-escrows.

Step 2: Check .env configuration
