test: add unit tests for MCP factory, context injection, JSON utils, and non-TTY install
59 tests across 4 files covering: - context-injection: tag injection, replacement, headerLine support, idempotency - json-utils: missing/valid/corrupt JSON handling with generic types - mcp-integrations: factory function, process.execPath, idempotency, merge behavior - install-non-tty: isInteractive detection, runTasks fallback, log wrapper Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
