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.
