Improve test coverage for lcpctl command branches

[amirHdev]

The operator CLI is useful, but some command paths still are not tested as well as they should be.

I’d like someone to add tests around the less-covered command and error branches in lcpctl.

Good targets:

• usage/help-style branches
• missing required flag or input cases
• unhappy-path request handling where the command should fail cleanly
• any small branch that is easy to cover without rewriting the command structure

Suggested files:

• cmd/lcpctl/main.go
• cmd/lcpctl/main_test.go

Acceptance criteria:

• tests improve branch coverage in a meaningful way
• command behavior stays unchanged unless there is an obvious bug
• go test ./... passes

Notes:
This is a nice issue if you prefer user-facing code over lower-level internals.
