Sprint 235 Plan: Native-First Semantic Expansion Policy

Goal

Prevent semantic task expansion from overriding already-strong native decomposition while preserving deterministic fallback for underspecified outputs.

Steps

• Step 2217: Add semantic expansion policy mode (always vs fallback_only).
• Step 2218: Compute native decomposition signals before semantic expansion.
• Step 2219: Apply expansion only when native decomposition is too shallow under fallback_only.
• Step 2220: Emit expansion telemetry with fallback decision metadata.
• Step 2221: Distinguish "feature disabled" from "enabled but skipped" in summary output.
• Step 2222: Add Sprint235IntegrationSummary.h and execution tracker.
