🧹 Refactor broadcastEvent to use generics instead of any

[Ayush-Vish]

This PR improves the code health of the GatewayServer by replacing the explicit any type in the broadcastEvent method with a TypeScript generic.

🎯 What: The broadcastEvent method's payload parameter was changed from any to a generic type T.
💡 Why: This enhances maintainability and readability by ensuring that the payload type is correctly tracked from the caller to the event creation logic, reducing the risk of runtime errors due to incorrect data structures.
✅ Verification: Verified the code changes via read_file and confirmed that the TypeScript syntax is correct. npm test was run, although it is currently a placeholder in the repository.
✨ Result: Improved type safety in the gateway communication layer.

📝 Walkthrough

Walkthrough

The gateway server's broadcastEvent method signature was changed from an untyped any payload to a TypeScript generic parameter <T>. Documentation (DESIGN_CHOICES.md) was updated to describe the "Gateway Server Type Safety (Broadcast Event)" design choice. Runtime behavior and control flow are unchanged.

Changes

Cohort / File(s)	Summary
Design doc + gateway server DESIGN_CHOICES.md, src/daemon/gateway/server.ts	Added a design-choice section describing "Gateway Server Type Safety (Broadcast Event)". Refactored GatewayServer.broadcastEvent signature from payload?: any to broadcastEvent<T>(eventName: string, payload?: T), carrying the generic through to createEvent.

Poem

🐰 A tiny rabbit taps the key,
<T> hops in where any used to be.
Payloads now wear tidy coats,
No more type-guessing in the moats.
The gateway sings—typed hops, whee! 🥕✨

Pull request overview

Refactors the gateway daemon’s GatewayServer.broadcastEvent signature to avoid any and improve type propagation into protocol event creation, and documents the design choice.

Changes:

• Updated GatewayServer.broadcastEvent to be generic (<T>) instead of accepting payload?: any.
• Added a short DESIGN_CHOICES.md note explaining the type-safety refactor.

Reviewed changes

Copilot reviewed 2 out of 2 changed files in this pull request and generated no comments.

File	Description
src/daemon/gateway/server.ts	Makes broadcastEvent generic so payload types can be inferred/checked at the call site and flow into createEvent.
DESIGN_CHOICES.md	Documents the rationale and intended benefit of the broadcastEvent typing change.
