Deploy eve projects on Zavu

Zavu compiles an eve-layout project into a first-class Zavu agent. The user's files are never edited: agent/instructions.md becomes the system prompt, each agent/tools/<name>.ts becomes a tool named <name>, and Zod inputSchema objects are converted to JSON Schema automatically.

Commands

# Import from GitHub and deploy in one step (also works for Zavu-native repos):
npx zavudev import owner/repo --sender sndr_123
npx zavudev import owner/repo#branch --root apps/agent   # monorepo / branch
# Private repos: set GITHUB_TOKEN in the environment (sent only to GitHub).

# Deploy a local eve project (detected by agent/instructions.md):
cd my-eve-agent && npx zavudev deploy --sender sndr_123
