[deep-report] Port pkg/agentdrain/README.md into a doc.go (no new writing)

[github-actions]

Description

pkg/agentdrain has rich README.md content (68 exported symbols) but no doc.go, so godoc/pkg.go.dev tooling cannot surface its package documentation. Reformat the existing README prose into a // Package agentdrain ... comment in a new pkg/agentdrain/doc.go. (Verified: README.md present, doc.go absent.)

Expected Impact

Package docs become discoverable via standard Go tooling with zero new content authoring — pure reformatting. Highest-ROI doc gap per the repository-quality scan.

Suggested Agent

Repository Quality / Documentation agent.
