Fork of deepsec: Codex Daybreak default, Pi second, pluggable sandboxes (00b895e)

@aryasaatvik/deepsec is a fork of vercel-labs/deepsec tuned for this
workspace:

• Codex is the default harness with daybreak-blue-latest; Pi is the second
  recommended harness, with OpenCode Go and OpenAI Codex subscription presets.
• Sandbox execution is provider-pluggable: a SandboxProvider interface with a
  Vercel adapter and a local reference adapter, selected with
  --sandbox-provider.
• The fork builds and publishes with pnpm 12; packages/website is kept in-tree
  but excluded from the workspace.
