fix: resolve TypeScript errors, missing development dependencies and refactor README

[praptisharma28]

Issues Fixed

This PR resolves several development blockers that prevent the Eremos framework from running out of the box:

1. Missing Development Dependencies

• Problem: Repository uses TypeScript but lacks required devDependencies
• Fix: Added typescript, ts-node, and @types/node to enable development
• Impact: Developers can now run npm install and execute TypeScript code

2. Broken Script Imports

• Problem: scripts/export-agent-memory.ts imports from "../agents" but no index file exists
• Fix: Created agents/index.ts that exports all agents and provides a registry array
• Impact: Scripts can now access agents programmatically without filesystem scanning

3. TypeScript Compilation Error

• Problem: agents/launchtracker.ts passes confidence to logSignal() but the interface doesn't accept it
• Error: TS2353: Object literal may only specify known properties, and 'confidence' does not exist
• Fix: Added optional confidence?: number property to logSignal interface
• Impact: Preserves the agent confidence scoring feature described in the README

4. Outdated / Incomplete README

• Problem: The README lacked setup instructions and did not reflect the latest dev workflow
• Fix: Refactored README with updated installation, development, and usage guidelines
• Impact: New contributors can now set up and run the project smoothly without guesswork

Testing

# Install dependencies
npm install

# Verify TypeScript compilation
npx tsc --noEmit

# Test agent imports work
npx ts-node -e "import('./agents/index').then(m => console.log('Loaded', m.agents.length, 'agents'))"

# Test previously broken script
npx ts-node scripts/export-agent-memory.ts
