Review test coverage

Summary

This PR fixes a type safety issue in packages/rivetkit/src/actor/generic-conn-driver.ts where ws.raw was being cast directly to WebSocket without accounting for it potentially being undefined. The fix adds proper null safety checks in two locations.

Changes Analysis

The PR makes targeted changes to two methods in the WebSocket driver:

Lines 130-134 (disconnect method):

// Before:
const raw = ws.raw as WebSocket;

// After: 
const raw = ws.raw as WebSocket | undefined;
if (!raw) {
    actor.rLog.warn({ msg: "ws.raw does not exist" });
    return;
}

Lines 159-160 (getConnectionReadyState method):

// Before:
const raw = ws.raw as WebSocket;

// After:
const raw = ws.raw as WebSocket | undefined;
if (!raw) return undefined;

Code Quality Assessment

✅ Positive Aspects

Defensive Programming: The changes implement proper null safety, preventing potential runtime errors when ws.raw is unexpectedly undefined.
Type Safety Improvement: Correctly typing ws.raw as WebSocket | undefined instead of assuming it's always present aligns with TypeScript best practices.
Consistent Error Handling: The disconnect method maintains consistent warning patterns already established in the codebase for similar scenarios.
Minimal, Surgical Change: The fix is focused and only addresses the specific issue without unnecessary refactoring.
Follows Repository Guidelines: Adheres to CLAUDE.md guidelines for lowercase log messages and structured logging patterns.

⚠️ Areas for Improvement

Inconsistent Null Handling:
- disconnect(): Returns early with a warning when raw is undefined
- getConnectionReadyState(): Returns undefined silently
- Suggestion: Add consistent warning logging in getConnectionReadyState():
```
if (!raw) {
    actor.rLog.warn({ 
        msg: "ws.raw does not exist for getConnectionReadyState", 
        connId: conn.id 
    });
    return undefined;
}
```
Missing Context Documentation: No explanation of when/why ws.raw might be undefined. This would help future maintainers understand the edge case.

Potential Issues & Bugs

No Critical Issues Found: The changes are safe and improve robustness. The fix prevents potential null pointer exceptions that could crash the connection handling.

Logical Correctness: Both methods now handle the undefined case appropriately:

disconnect() gracefully exits when there's nothing to disconnect
getConnectionReadyState() returns undefined indicating an unknown state

Performance Considerations

Negligible Impact: The additional null checks add minimal overhead (~1-2 CPU cycles per call). The performance benefit of preventing crashes far outweighs this cost.

Security Considerations

Low Risk, Positive Impact:

No new security vulnerabilities introduced
Improves system stability by preventing crashes
Defensive programming reduces attack surface for potential DoS scenarios

Test Coverage Concerns

Missing Test Cases: The codebase likely lacks tests covering scenarios where ws.raw is undefined.

Recommendations:

Add unit tests simulating undefined ws.raw for both methods
Integration tests for edge cases where Hono's WSContext.raw might not be available
Test graceful handling in both disconnect and connection state scenarios

Architecture & Design

Appropriate Solution: The fix addresses the symptom (undefined ws.raw) at the right level in the driver layer. However, it would be valuable to understand:

When does Hono's WSContext.raw become undefined?
Is this a legitimate state or an indication of an upstream issue?

Compliance with Repository Standards

✅ Follows CLAUDE.md logging guidelines (lowercase messages)
✅ Uses proper structured logging with context
✅ Maintains existing error handling patterns
✅ TypeScript strict mode compliance

Final Recommendation

✅ APPROVE: This is a solid defensive programming fix that improves type safety and prevents runtime errors.

Priority Improvements:

Add consistent warning logging in getConnectionReadyState()
Add test coverage for undefined ws.raw scenarios
Document when this condition occurs (PR description or code comments)

Risk Level: Very Low - Conservative change that only improves error handling without changing core logic.
