Sync Superpowers 6 manifest components

Publish the completed third-party sync output for Superpowers 6.0.2 and keep the marketplace PowerShell sync script aligned with the Python adapter's manifest-declared component copying.

Constraint: Superpowers now ships Codex hooks through .codex-plugin/plugin.json, and marketplace validation requires the referenced hook path to exist.
Rejected: Commit the partially synced tree without hooks | Codex install would carry a manifest pointing at a missing hooks file.
Confidence: high
Scope-risk: moderate
Directive: Preserve normal incremental marketplace history; do not rewrite history for ordinary source updates.
Tested: /Users/eapil/git/keyinfo/.venv/bin/python3 scripts/validate_marketplace.py; rg public-secret scan; Codex temp CODEX_HOME marketplace add/list/add superpowers and hook cache checks.
Not-tested: PowerShell script execution because pwsh/powershell is not installed locally; live hook execution inside an interactive Codex session.
