## Summary
The `EventLoopTimer.Arm` result from `EventLoopTimer.fire()` was being
ignored at both call sites. This PR removes the unused return type and
simplifies the code.
## Changes
- Changed `EventLoopTimer.fire()` to return `void` instead of `Arm`
- Updated all 15 timer callback functions to return `void`
- Removed the `Arm` type definition
- Simplified the `drainTimers()` loop that was ignoring the return value
- Updated both call sites in `Timer.zig`
## Details
The `.rearm` functionality was unused - timers that need to reschedule
themselves (like DNS resolver) handle this by calling
`addTimer()`/`update()` directly rather than relying on the return
value.
This change removes:
- The `Arm` union enum type (3 lines)
- All `return .disarm` and `return .{ .rearm = ... }` statements
- The switch statement in `drainTimers()` that did nothing with the
return value
Net result: **-58 lines** of dead code removed.
## Testing
- [x] Bun builds successfully with `bun bd`
