Per Phase 1 audit at cowork/docs-overhaul-phase-1-audit-2026-05-04/.
Phase 2 organizes docs/ into eight audience-aligned subdirectories
(getting-started, reference, operator, migration, compliance,
contributor, archive). docs/README.md will be the navigation index
linking into each.
This commit only adds the placeholder. Subdirectories materialize as
Phase 2 file moves land. Index gets populated in Phase 12 once all
moves and content edits are complete.
