BreakevenContract

Contract for breakeven events.

Emitted by breakevenSubject when a signal's stop-loss is moved to breakeven (entry price). Used for tracking risk reduction milestones and monitoring strategy safety.

Events are emitted only once per signal (idempotent - protected by ClientBreakeven state). Breakeven is triggered when price moves far enough in profit direction to cover transaction costs.

Consumers:

• BreakevenMarkdownService: Accumulates events for report generation
• User callbacks via listenBreakeven() / listenBreakevenOnce()
