multi-tenancy: promote workspaces to top-level table Block A of the EchoDo plan. Workspaces used to live as `objects(type='workspace')`, which made it impossible to put a real RLS-friendly tenant boundary on the schema or to give each workspace a stable URL slug. This commit: - Adds a top-level `workspaces` table (slug unique, owner FK, plan_tier hook). - Migrates the 8 anchor tables (objects, workspace_members, object_type_defs, property_definitions, templates, forms, markdown_backlog_items, cursor_sync_mappings) to FK into `workspaces.id` instead of `objects.id`, with a hand-augmented data-copy migration that preserves IDs and slug-collision- proofs on backfill. - Introduces a `workspaceProcedure` tRPC middleware + `resolveWorkspace` helper that take a UUID-or-slug `workspace` handle and expose `ctx.workspace`. All tenant-scoped routers (objects, types, properties, templates, forms, search, ai, relations, favorites) now flow through it. - Updates the web app to pass `workspace` slugs from the URL (or store) instead of the old `workspaceId`, including a workspace-sync layer that rewrites /<UUID>/... links to /<slug>/... - Updates the MCP tools (list_objects, create_object, search_objects) and the workspace://{handle}/tree resource to accept either a slug or UUID so existing agents keep working. - Adds a Create Workspace dialog and a Workspace Settings page (rename + slug rename with redirect, owner-only archive). Verified locally against a fresh Postgres: migration applies cleanly, slug uniqueness holds, tenant data is isolated by workspace_id, slug↔UUID resolution works in both directions, and ON DELETE CASCADE cleans up child rows in the correct workspace only.
