feat(inquirerer): add boolean alias and json question types

Summary

Adds two new question types to inquirerer:

• boolean — Semantic alias for confirm. Routes to the same y/n handler but provides a more natural type name when generating CLI prompts from schema types where the field is Boolean.
• json — New handler that accepts raw JSON string input, validates with JSON.parse(), and returns the parsed object. Shows a (JSON) hint in the prompt. Returns null for invalid JSON.

Also fixes a pre-existing test isolation bug where inputQueue/currentInputIndex weren't reset between tests in beforeEach.

Review & Testing Checklist for Human

• json() return type is Record<string, unknown> but JSON.parse() can return arrays, primitives, etc. Verify this is intentionally restrictive or should be widened to unknown
• Invalid JSON silently returns null instead of re-prompting or showing a parse error message. Confirm this is acceptable UX for interactive use — users get no feedback about why their input was rejected
• as unknown as ConfirmQuestion cast in handleQuestionType for the boolean case — works because confirm() only reads question.default (which is boolean on both types), but is fragile if confirm() ever reads a ConfirmQuestion-specific property
• json() noTty path returns implicit undefined (via bare return;) when no default exists, which doesn't match the declared return type Promise<Record<string, unknown> | null>. Check if this causes downstream issues

Recommended test: Run the test suite locally with npx jest --config jest.config.js from packages/inquirerer/ and verify all 150 tests pass.
