Network and kubernetes instability in extended use sessions

### Description

If I leave my colima/kubernetes running for some time, it destabilizes unpredictably. The two signs of that happening are:

1. I start seeing network connectivity errors from various services
2. If I clean up all deployments and services, all pods get stuck in Terminating.

### Version

colima version 0.6.7
git commit: ba1be00e9aec47f2c1ffdacfb7e428e465f0b58a

runtime: docker
arch: x86_64
client: v24.0.7
server: v24.0.7
limactl version 0.19.1
qemu-img version 8.2.0

### Operating System

- [ ] macOS Intel <= 13 (Ventura)
- [ ] macOS Intel >= 14 (Sonoma)
- [ ] Apple Silicon <= 13 (Ventura)
- [X] Apple Silicon >= 14 (Sonoma)
- [ ] Linux

### Output of `colima status`

INFO[0000] colima is running using QEMU
INFO[0000] arch: x86_64
INFO[0000] runtime: docker
INFO[0000] mountType: sshfs
INFO[0001] socket: unix:///Users/aran/.colima/default/docker.sock
INFO[0001] kubernetes: enabled

### Reproduction Steps

I run a variety of services on Kubernetes and just let it sit. I use a tool called Skaffold to deploy to the local Kubernetes. It uses docker to load containers directly. When errors crop up everywhere, I kill Skaffold and it deletes the services and deployments. At that point I see all pods stay in Terminating status. If I restart colima, when it comes back up, those pods then finish Terminating normally.

### Expected behaviour

Pods retain connectivity and always terminate normally within colima kubernetes instance.

### Additional context

Kubernetes version v1.28.3+k3s2
M2, Sonoma 14.2.1, 24GB RAM
cpu: 3
disk: 60
memory: 16

The issue describes network and pod termination instability in colima's Kubernetes runtime after extended use. Start by examining the colima source code for network handling and pod lifecycle management, particularly around the k3s integration. Reproduce the issue by leaving a colima instance running with deployments, then check logs and network connectivity. Look for existing tests related to Kubernetes stability or network issues.
