chore: retrigger CI after rebase to main

Covers: loading/empty/event-list states, event_type color mapping,
expand/collapse with aria-expanded/aria-controls, refresh button,
error state from API rejection, auto-refresh interval via setInterval mock,
and unmount cleanup.

Key patterns:
- vi.hoisted() for module-level api mock (vi.mock hoisting)
- vi.useRealTimers() for non-timing tests; spyOn(setInterval/clearInterval)
  for auto-refresh tests to avoid Vitest fake-timer infinite loops
- fireEvent.click + native .click() via act() for expand/collapse
- Re-query DOM after state flush to avoid stale element references

+ *   - Tab switching between all available tabs

+ *   - "I've saved it — close" calls onClose
+ *   - Security warning: one-time token display
+ *   - Fields tab shows raw values

- * Tests for MemoryTab — the workspace KV memory tab.
- *
- * Coverage:
- *   - Loading state (pending GET)
- *   - Empty state ("No memory entries")
- *   - Memory entries list renders
- *   - Expand/collapse entry + aria-expanded
- *   - Add entry: key validation, value JSON parsing, TTL
- *   - Edit entry: begin, cancel, save, 409 conflict
- *   - Delete entry: optimistic removal
- *   - Error state from API failure
- *   - Refresh button triggers reload
- *   - Awareness dashboard collapse/expand
- *   - Advanced toggle shows/hides KV section
- *   - Awareness URL includes workspaceId
- *
- * Uses vi.useRealTimers() + flush() pattern for all non-window tests.
- * window.open is mocked per-test since it is environment-dependent.

-//
-// Background (#2872 + post-2026-05-06 follow-up):
-//   - Migration 20260506000000_workspaces_unique_parent_name added a
-//     partial UNIQUE index on (COALESCE(parent_id, sentinel), name)
-//     WHERE status != 'removed'. It exists to close the TOCTOU race in
-//     /org/import that previously let two concurrent POSTs both INSERT
-//     the same (parent_id, name) row.
-//   - /org/import handles the constraint via `ON CONFLICT DO NOTHING`
-//     + idempotent re-select (handlers/org_import.go).
-//   - The Canvas Create handler (handlers/workspace.go) did NOT — a
-//     duplicate POST returned an opaque HTTP 500 with the raw pq error
-//     in the server log. Repro path: user clicks a template card twice
-//     in canvas before the first response paints.
-//
-// Resolution: auto-suffix the user-typed name on collision. The
-// uniqueness constraint required for #2872 stays in place; only the
-// Canvas Create path's reaction to it changes. Names become a
-// free-form display label that the platform disambiguates; row
-// identity is carried by the workspace id (UUID).
-//
-// Suffix shape: " (2)", " (3)", … up to N=maxNameSuffix. Chosen over
-// numeric "-2" / "_2" because the parenthesised form is the standard
-// disambiguation pattern users already expect from Finder / Explorer
-// / Google Docs / file managers. Stays under the 255-char name cap
-// (#688 — validated by validateWorkspaceFields) for any reasonable
-// base name; parens are not in yamlSpecialChars so the existing YAML-

-// ------------------------------
-// sqlmock CANNOT verify the actual partial-unique-index

-// the helper's retry contract under a fake driver error, but only
-// a real Postgres can confirm:
-//
-//   - The migration 20260506000000 actually created the index.
-//   - lib/pq emits SQLSTATE 23505 with Constraint =
-//     "workspaces_parent_name_uniq" (not a synonym, not the message
-//     fallback).
-//   - The COALESCE(parent_id, sentinel) target collapses NULL
-//     parent_ids so two root-level workspaces with the same name
-//     collide as the migration intends.
-//   - The WHERE status != 'removed' partial filter exempts
-//     tombstoned rows from blocking re-use.
-//
-// Per feedback_mandatory_local_e2e_before_ship: ship-mode requires
-// the helper to be exercised against a real Postgres before the PR
-// merges.
