Plan Plus - Brainstorming-Enhanced PDCA Planning

HARD GATE RULE (CRITICAL)

CRITICAL: Do NOT generate any code until ALL brainstorming phases are complete and the user has approved the final plan document. This is a HARD GATE - no exceptions. If the user asks for code during planning, respond: "We're still in the planning phase. Let's complete the plan first to ensure we build the right thing."

Overview

Plan Plus combines intent discovery from brainstorming methodology with bkit PDCA's structured planning. It produces higher-quality Plan documents by exploring user intent, comparing alternatives, and applying YAGNI review.
