fix: Gateway CLI consistency — ANSI stripping, missing tests, --kubeconfig

[robbycochran]

Problems

ProviderList missing ANSI stripping

cli.go ProviderList does not strip ANSI codes before parsing. SandboxList, GatewayList, InferenceModel, and ActiveGateway all do. ProviderList is the only parser that skips this.

Fix: Add cleaned := ansiRE.ReplaceAllString(line, "") before strings.Fields(line) in ProviderList.

Missing tests for output-parsing methods

cli_test.go has tests for ProviderList, ProviderGet, InferenceGet, SandboxCreate, SandboxDelete — but zero coverage for:

• GatewayList (complex branching for * active marker)
• SandboxList (ANSI stripping)
• InferenceModel (Model: line parsing)
• ActiveGateway (* prefix parsing)
• CLIVersion, CLIPath

Fix: Add stub-script tests using the existing writeStub pattern.

deploy --remote --kubeconfig not forwarded

Bash deploy.sh accepts --kubeconfig and exports it. Go deploy.go hardcodes only --remote when delegating to the bash script. Users running harness deploy --remote --kubeconfig /path get an unknown-flag error.

Fix: Forward all extra args to the bash script, or add --kubeconfig flag and pass it through.

Severity: Medium
