Add Docker API version negotiation to fix daemon compatibility

[Copilot]

Docker client was hardcoded to API v1.43, causing failures with daemons requiring v1.44+:

failed to pull image: Error response from daemon: client version 1.43 is too old. 
Minimum supported API version is 1.44

Changes

Added client.WithAPIVersionNegotiation() to all Docker client instantiations:

• internal/proc/container.go - Run() and stop() methods
• hack/examples.go - updateExample() function

// Before
cli, err := client.NewClientWithOpts(client.FromEnv)

// After
cli, err := client.NewClientWithOpts(client.FromEnv, client.WithAPIVersionNegotiation())

Client now auto-negotiates API version on first request, maintaining compatibility with both older and newer Docker daemons.

Original prompt

[dynamodb] (failed) failed to pull image: Error response from daemon: client version 1.43 is too old. Minimum supported API version is 1.44, please upgrade your client to a newer version
