fix(canvas/ContextMenu): prevent React error #185 by moving hasChildren derivation out of Zustand selector

ContextMenu used `.some()` inside its Zustand selector to compute hasChildren.
Zustand's useSyncExternalStore calls the selector on every snapshot; `.some()`
returns a new boolean each time, which React 19's stricter comparison
and the re-render side-effects from the store subscription created a
feedback loop on mobile Chat tab mount → React error #185
("Maximum update depth exceeded").

Fix: select the stable `nodes` array once, derive children via useMemo
outside the store subscription. Also removes the inline `getState().nodes.filter()`
call in handleDelete in favour of the memoized children.

Regression tests (2 cases):
- setPendingDelete receives correct children array when workspace has children
- setPendingDelete hasChildren=false and empty children when no children

-# Comprehensive Playwright E2E for the unified chat stack (desktop
-# ChatTab + mobile MobileChat). Runs on every PR that touches canvas,
-# workspace-server, or this workflow file.
-#
-# Architecture:
-#   1. Ephemeral Postgres + Redis (docker, unique container names)
-#   2. workspace-server built from source, started with
-#      MOLECULE_ENV=development (fail-open auth)
-#   3. canvas dev server (npm run dev) on :3000
-#   4. Playwright tests create workspaces via API, point them at an
-#      in-process echo runtime, and exercise the full send/receive
-#      round-trip through the browser.
-#
-# Parallel-safety: same pattern as e2e-api.yml — per-run container names
-# and ephemeral host ports so concurrent jobs on the host-network runner
-# don't collide.

- *   - isDeployingRoot: true when any descendant is "provisioning"
- *   - isActivelyProvisioning: true only for the node itself in that state
- *   - isLockedChild: true for non-root nodes in a deploying tree

- *   - descendantProvisioningCount: non-zero only on root nodes
- *   - Performance contract: O(n) single-pass walk — tested by verifying
- *     correctness across 50-node trees (n=50, all cases above)
