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 Refs: #651 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
test(canvas/lib): add isExternalLikeRuntime coverage (16 cases)

+ * Tests for ExternalConnectModal — the modal surfaced after creating a
+ * runtime="external" workspace. Surfaces workspace_auth_token + ready-to-paste
+ * snippets so the operator can configure their off-host agent.
+ *
+ * Coverage:
+ *   - Renders nothing when info=null
+ *   - Opens dialog when info is provided
+ *   - Default tab: "Universal MCP" when universal_mcp_snippet present, else "Python SDK"
+ *   - Tab switching between all available tabs
+ *   - Snippets show with auth_token replacing placeholders
+ *   - Copy button: calls clipboard API, shows "Copied!", clears after 1.5s
+ *   - Copy failure: shows fallback textarea
+ *   - "I've saved it — close" calls onClose
+ *   - Security warning: one-time token display
+ *   - Fields tab shows raw values
+ *   - Tabs hidden when their snippet is absent
+ *
+ * Fake timers: applied per-describe to avoid mixing with waitFor. Tests that
+ * use waitFor (which needs real timers) run without fake timers. Tests that
+ * verify setTimeout behavior use vi.useFakeTimers() + act(vi.advanceTimersByTime).

+ * The function takes a flat list of NodeProjections and a set of
+ * deletingIds, then computes per-node OrgDeployState:
+ *   isActivelyProvisioning — node itself is provisioning
+ *   isDeployingRoot       — node is a root AND has provisioning descendants
+ *   isLockedChild         — node is a deleting child OR a non-root in a deploying tree
+ *   descendantProvisioningCount — total provisioning descendants (roots only)
+ *
+ * Coverage:
+ *   §1  Empty input
+ *   §2  Single node — no parent, non-provisioning
+ *   §3  Single node — no parent, provisioning
+ *   §4  Single node — has parent (parent exists)
+ *   §5  Parent not in projections → node treated as root
+ *   §6  Two nodes: root (non-provisioning) + child
+ *   §7  Two nodes: root (provisioning) + child
+ *   §8  Three-level tree: grandparent (provisioning) → parent → child
+ *   §9  DeletingIds contains a non-root node → isLockedChild=true
+ *   §10 DeletingIds contains the root → root isLockedChild=true
+ *   §11 Two independent roots, one provisioning
+ *   §12 Provisioning count: root has 2 provisioning descendants
+ *   §13 Non-root node with provisioning status → isActivelyProvisioning=true
+ *   §14 findRoot memoization: repeated calls don't re-walk the chain
+ *   §15 deletingIds + provisioning interact: deleting takes isLockedChild
+ *   §16 Child of provisioning root (not itself provisioning) → isLockedChild=true

- * refresh button, auto-refresh setup.
+ * Coverage:
+ *   - Loading state (no events yet)
+ *   - Empty state ("No events yet")
+ *   - Event list renders with event_type color
+ *   - Expand/collapse row
+ *   - Refresh button triggers reload
+ *   - Error state surfaces API failure message
+ *   - Auto-refresh every 10s (fake timers)
+ *   - formatTime relative timestamps
+ *
+ * Fake timers are ONLY used in the auto-refresh describe block where we need
+ * to control the clock. All other tests use real timers so Promises resolve

- * Tests for ScheduleTab component.
+ * Tests for ScheduleTab — cron-based task scheduling.
 *
- * Covers: cronToHuman pure function, relativeTime pure function,
- * loading/error/empty states, schedule list rendering.
+ * Coverage:
+ *   - Loading state
+ *   - Empty state (no schedules)
+ *   - Schedule list rendering (single + multiple)
+ *   - Status dot color (error/ok/idle)
+ *   - Toggle enable/disable via status dot
+ *   - Delete via ConfirmDialog
+ *   - Run Now button triggers POST + POST
+ *   - Create schedule form open/close
+ *   - Edit schedule form pre-fills values
+ *   - Form validation (disabled when cron/prompt empty)
+ *   - Create POST with correct payload
+ *   - Edit PATCH with correct payload
+ *   - Error state surfaces API failures
+ *   - Auto-refresh every 10s (spy)
+ *   - cronToHuman formatting
+ *   - relativeTime formatting
+ *   - Reset form clears all fields
+ *   - Disabled schedules are visually dimmed

- * Tests for AttachmentViews.tsx — PendingAttachmentPill + AttachmentChip.
+ * AttachmentViews — pure presentational components for chat attachments.
 *
- * 16 cases covering:
- * - PendingAttachmentPill: name, size, aria-label, onRemove, one-button guard
- * - AttachmentChip: name+glyph, size, no-size, title, onDownload, tone=user/agent, one-button guard
+ * Covers:
+ *   - PendingAttachmentPill renders file name, formatted size, × button
+ *   - PendingAttachmentPill × button has correct aria-label
+ *   - PendingAttachmentPill calls onRemove when × clicked
+ *   - PendingAttachmentPill renders exactly one button
+ *   - AttachmentChip renders attachment name and download glyph
+ *   - AttachmentChip renders size when provided
+ *   - AttachmentChip omits size span when size is undefined
+ *   - AttachmentChip calls onDownload(attachment) on click
+ *   - AttachmentChip title attribute for hover tooltip
+ *   - AttachmentChip tone=user applies blue accent classes
+ *   - AttachmentChip tone=agent applies surface classes
+ *   - AttachmentChip renders exactly one button
 *
- * Pattern: render the real component, inspect actual DOM output.
- * No mocking of the components themselves.
+ * NOTE: No @testing-library/jest-dom import — use textContent / className /
+ * getAttribute checks to avoid "expect is not defined" errors in this vitest
+ * configuration.
