fix: improve activeModelEntries consistency and validation

[hobostay]

Summary

This PR improves the activeModelEntries function in nemoclaw/src/index.ts to:

1. Add consistency: All model IDs now use the inference/ prefix (both default and configured models)
2. Add validation: Explicit check for non-empty model string before using configured model
3. Improve clarity: Extract configuredModel variable for better code readability

Changes

Before

• Default models had IDs like nvidia/nemotron-3-super-120b-a12b
• Configured models had IDs like inference/moonshotai/kimi-k2.5
• Inconsistent format between default and configured models
• No explicit check for empty strings

After

• All models consistently use the inference/ prefix
• Default models: inference/nvidia/nemotron-3-super-120b-a12b
• Configured models: inference/moonshotai/kimi-k2.5
• Added .trim().length > 0 check to handle empty/whitespace strings

Testing

The change is defensive and maintains backward compatibility:

• When onboardCfg is null/undefined or model is empty → returns default models
• When a valid model is configured → returns that model with inference/ prefix

Related Issues

This addresses potential edge cases in model registration that could cause confusion when:

• A config object exists but the model property is undefined/empty
• Model entries have inconsistent ID formats

📝 Walkthrough

Walkthrough

The activeModelEntries function in index.ts was refactored to prioritize a configured model when onboardCfg.model is present and non-empty. It returns a model entry with inference/${configuredModel} as the ID; otherwise it returns predefined defaults with explicit inference/nvidia/... format IDs. Inline comments document the selection behavior.

Changes

Cohort / File(s)	Summary
Model Selection Logic nemoclaw/src/index.ts	Refactored activeModelEntries to select a single configured model when available, using explicit inference/nvidia/... ID format for defaults. Added clarifying inline comments documenting configured vs default selection behavior.

Trim the configured model value to prevent whitespace in ID and label.

The validation checks configuredModel.trim().length > 0, but the untrimmed value is used in the ID and label. If the model config has leading/trailing whitespace (e.g., from manual JSON editing), it would create an invalid ID like "inference/ nvidia/model ".

Apply .trim() at assignment:

Proposed fix

  const configuredModel = onboardCfg?.model;
  if (configuredModel && configuredModel.trim().length > 0) {
    return [
      {
-       id: `inference/${configuredModel}`,
+       id: `inference/${configuredModel.trim()}`,
-       label: configuredModel,
+       label: configuredModel.trim(),
