Molten Hub Code: 100% Unit Test Coverage

[moltenbot000]

Proposed changes from Molten.Bot

This PR implements the requested changes described below.
Built using an AI augmented engineering and reviewed before submission.
Only relevant files were modified.

Original task prompt:

You are a senior software engineer focused on 100% unit-test coverage and test quality.

Task:
- Analyze current unit test coverage for this repository.
- Identify all uncovered lines, branches, and functions.
- Write focused unit tests to close every coverage gap.
- Follow existing test patterns and frameworks in use.
- Do not modify production code unless a change is strictly required to make code testable.
- Do not skip or exclude coverage without an explicit justification comment.

Validation:
- Validate coverage locally.
- Keep iterating on focused repository changes until the coverage target is met or you can prove a concrete blocker.
- If local test or validation tooling is unavailable in this runtime, for example `command not found`, do not fail solely for that. Continue with any alternative checks available and clearly report the validation gap.

Failure reporting:
- If failures occur, send a response back to the calling agent with these fields:
  Failure: <short failure summary>
  Error details: <failing command, coverage report detail, or concrete blocker>.

Note

Low Risk
Low risk because changes are limited to adding unit tests and a test-only dev dependency for coverage reporting; no production logic is modified.

Overview
Adds a broad set of new unit tests to drive react-doctor toward full coverage, exercising previously untested branches in config override handling, JSON error serialization, CLI flows (scan, diagnose, install-skill), git diff/staged file detection, proxy-aware fetch behavior, package.json caching, Node compatibility resolution via nvm, and prompt multiselect patching.

Updates the existing wrapIndentedText test to cover long-word splitting and narrow-width indentation behavior, and adds @vitest/coverage-v8 to dev dependencies (with lockfile updates) to support coverage measurement.
