docs: add V2 technical report with 370-task multi-run results

- Fix stale statistics in selected_benchmark_tasks.json (total_tasks 390→370,
  tasks_per_benchmark corrected to match actual per_suite counts)
- Rerun comprehensive analysis, eval report, and IR retrieval pipeline
  (normalize + compute metrics + impact analysis) on all 429 official runs
- Create TECHNICAL_REPORT_V2.md with updated results:
  - 370 tasks (150 SDLC + 220 Org), 4132 individual results, 3+ runs/task
  - Overall MCP delta: +0.025 (CI: [+0.008, +0.042])
  - SDLC delta: +0.014 (CI spans zero, not significant)
  - Org delta: +0.032 (CI: [+0.013, +0.053])
  - IR metrics: 1745 computable tasks, file recall 0.390
  - V1→V2 comparison table documenting how multi-run averaging
    reduces noise and narrows CIs vs single-trial V1 data
- Architecture diagram updated for 9 SDLC + 11 Org suites
- Execution infrastructure updated for Daytona cloud, 3 accounts
