  run-parallel-100.ps1 - orchestrate 100-article SEO restoration with parallel Sonnet /goal agents.
  Run from the odoo-expertos repo root.
  Phases:
    setup    -> SETUP.txt on fix/seo-all (brand, persona, flow, strategy, clusters, z-image probe). Serial.
    batches  -> B01..B10.txt in parallel git worktrees, each on its own fix/seo-batch-bNN branch.
    final    -> FINAL.txt on fix/seo-all (merge all batches, W5b, clusters exec, REVIEW gate, deploy, re-audit).
    all      -> setup -> batches -> final.

  Examples:
    .\seo-audit-2026-05-27\run-parallel-100.ps1                  # all phases, max 10 concurrent
    .\seo-audit-2026-05-27\run-parallel-100.ps1 -Phase setup     # just setup
    .\seo-audit-2026-05-27\run-parallel-100.ps1 -Phase batches -MaxConcurrent 5
    .\seo-audit-2026-05-27\run-parallel-100.ps1 -Phase final
