Add --yes flag to deploy and fix for explicit non-interactive / CI mode

[AK11105]

What problem does this solve?

CI pipelines have no reliable way to run deploy or fix non-interactively. The current _is_interactive() detection is implicit and fragile — it checks whether stdin is a TTY, which varies by CI environment. There is no explicit flag to say "skip all prompts, use defaults or provided values."

Proposed solution

Add --yes to both deploy and fix subcommands. When set:

• Skips all confirmation prompts
• Skips clarifying questions from the LLM interpretation stage (A3)
• Uses suggested_sample_input from interpretation automatically if no --sample-input was provided
• Replaces all implicit _is_interactive() checks for prompt-skipping logic

inference-engine deploy ./model.pkl \
  --name sentiment --version v1 \
  --device cpu --routing static \
  --sample-input "great movie" --yes

inference-engine fix models/sentiment/v1/ --sample-input "great movie" --yes

All future commands must support --yes from the start. Do not add new commands that rely solely on _is_interactive().

Alternatives considered

Relying on _is_interactive() alone. This is already causing issues (see #19 ) and will continue to as more CI environments are used.
