This change introduces an ultra-minimal Core SI skeleton and moves domain-specific workflows into modular Instruction Deltas within dynamic skills. - Reduced Core SI from ~2000 to ~320 tokens. - Added Self-Correction and Precision mandates. - Implemented polymorphic snippet variants in PromptProvider. - Extracted Software Engineering and New Application workflows to skills. - Optimized tool descriptions for Gemini 3 Flash. - Fixed pre-existing build errors in useGeminiStream.ts.
