Sprint 256 Plan: Top-Gap Weighted Raw Candidate Selection

Goal

Use prioritized raw-gap backlog signals directly in raw-only candidate scoring so variant selection is guided by historically missing intrinsic signals, not only profile fail count.

Steps

• Step 2326: Extend raw candidate scorer with optional top-gap backlog input.
• Step 2327: Compute weighted top_gap_score and hit counts from candidate tasks.
• Step 2328: Add pipeline controls for weighted raw selection.
• Step 2329: Make raw candidate tie-break use top_gap_score when enabled.
• Step 2330: Emit baseline/best top-gap score telemetry in raw search summary.
• Step 2331: Add Sprint256IntegrationSummary.h and execution tracker.
