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>

+/**
+ * Tests for the non-TTY detection in the install command.
+ *
+ * The install command (src/npx-cli/commands/install.ts) has non-interactive
+ * fallbacks so it works in CI/CD, Docker, and piped environments where
+ * process.stdin.isTTY is undefined.
+ *
+ * Since isInteractive, runTasks, and log are not exported, we verify
+ * their presence and correctness via source inspection. This is a valid
+ * approach for testing private module-level constructs that can't be
+ * imported directly.
