--- Restores the workspaces.awareness_namespace column verbatim from

--- NULL on all rows after re-add — handlers no longer write to it and

--- Issue #1735 — drop the workspaces.awareness_namespace column.
---
--- "Awareness namespaces" were a memory-routing surface (env vars
--- AWARENESS_URL / AWARENESS_NAMESPACE) that was plumbed across the
--- platform but never wired in any production or staging environment
--- (verified 2026-05-23 via Railway GraphQL on the controlplane service:
--- AWARENESS_* unset in both env IDs 59227671-… and 639539ec-…).
---
--- The column added by migration 010_workspace_awareness.sql was only
--- ever populated with the canonical "workspace:<id>" string, which is
--- also the v2 memory namespace string (see internal/memory/namespace/
--- resolver.go:186). Removing the column does not change any agent-
--- visible memory namespace — handlers now compute the same
--- "workspace:<id>" string inline when inserting into agent_memories.
---
--- Related: #1733 (memory SSOT consolidation), #1734 (Memory tab bug).
