Summary

• Deletes @corbits/workflows's hub-mounted createWorkflowDetailRoute
  (GET /api/tenants/:tenantId/workflows/definitions/:id/detail) and
  createScheduledWorkflowRoutes (/api/tenants/:tenantId/workflows:
  scheduled list, scheduled run-now, available-catalog) from
  apps/hub/src/index.ts, per the owner ruling that workflow detail
  and schedule state ride on stock @intx/hub-api reads or stay a
  package-internal pure function — never a hub-composed route.
• apps/web/src/workflow-detail-api.ts now pages through stock's
  GET /api/tenants/:tenantId/workflows/definitions (there is no
  GET-by-id at all in stock) and stops at the matching id.
• apps/web/src/pages/workflow-detail-page.tsx renders exactly what
  stock exposes: name, description, status (deployed/stopped),
  current version. The former five-value lifecycle, source commit,
  steps table, and declared/approved grants + credential binding names
  are gone — stock has no manifest read, no wire projection, and no
  grant snapshot to derive them from.
• apps/web/src/routines-api.ts's listScheduledWorkflows and
  listAvailableCatalogWorkflows now resolve to an empty list rather
  than fetch a route that no longer exists (no stock-derivable
  ScheduleTrigger/cron read, no stock connection-satisfaction read);
  runScheduledWorkflowNow always rejects. The Routines page's
  existing empty states render as if no bench had a schedule.
• packages/workflows's browser-safe ./client keeps a thin
  WorkflowDefinitionDetail shape and workflowNotLaunchableReason
  narrowed to stock's two-value status. The pure schedule-state readers
  (listScheduledWorkflowDefinitions, listAvailableCatalogWorkflows,
  listDeployedCronDefinitions) stay as package-internal functions
  with no hub route, per the ruling.

Upstream ask (also filed on CL-8160)

Stock's WorkflowDefinitionResponse
(vendor/intx/types/src/workflows.ts) exposes only id, tenantId,
name, description, currentVersion, status
('deployed' | 'stopped'), createdAt, updatedAt — confirmed by
reading vendor/intx/hub-api/src/routes/workflow-definitions.ts
directly (list/versions/rollback, no GET-by-id). There is no manifest
read (a package's package.json corbits.workflow block), no wire
projection, no grant snapshot, and no asset display name anywhere in
stock. Asking for:

1. A workflow definition's package.json corbits.workflow block
   (title/description/icon/schedule) exposed through a stock read.
2. Either a GET /workflows/definitions/:id, or enough on the
   list/versions response to reconstruct a detail page without paging
   the whole list.
3. A stock-readable ScheduleTrigger/cron surface, so schedule state can
   be computed client-side from stock deployment reads as the ruling
   intends, and a stock connection-satisfaction read for the
   "Available" catalog-workflow section.

Without these, Routines' scheduled roster, run-now, pause/resume, and
Available section have no stock-derivable replacement and stay empty
until an upstream ask lands.

Deleted tests

• packages/workflows/src/detail/detail-route.drizzle.test.ts
• packages/workflows/src/detail/definition-lifecycle.test.ts
• packages/workflows/src/schedule/scheduled-route.test.ts
• apps/web/test/routines-available-section.test.tsx (whole file — the
  Available section has no stock-derivable data source)
• apps/web/test/routines-page.test.tsx's "RoutinesRoute —
  membership-based aggregation" suite (network-backed aggregation
  against the deleted /workflows/scheduled route)
• apps/web/test/routine-detail-page.test.tsx's "an id renders the
  scheduled workflow itself" case
• apps/web/src/shell/context-menu/items.test.tsx's run-now
  success-path case (the outcome it proved is no longer reachable)

Test plan

• bun run typecheck
• bun run check:structural (all checks pass, including
  browser-safe-subpaths on @corbits/workflows/client)
• bun --cwd packages/workflows test (148 pass, 10 DB-gated skip —
  no DATABASE_URL locally)
• bun --cwd apps/web test (791 pass)
• bun run lint fails on a pre-existing, unrelated formatting issue
  already on origin/main (AGENTS.md) — not touched by this PR
