+fix(action): honor the spec `disabled` predicate on every action-rendering surface (#1885 follow-through)
+
+The spec Action field is `disabled` (boolean | CEL — disabled when TRUE); the
+schema has no `enabled` key. #1885 wired it in `action:button` only. Browser
+dogfooding against the showcase found FIVE more surfaces where a spec-authored
+`disabled` silently did nothing:
+
+- **components** — the `action:group` leaves (inline + dropdown), `action:icon`
+  and `action:menu` still read the legacy non-spec `enabled`. They now consume
+  `disabled` as the primary control (evaluated in the same scope as `visible`),
+  with `enabled` kept as a deprecated fallback.
+- **app-shell** — `DeclaredActionsBar` (server-declared action bar) read
+  neither; it gains `disabled` (no legacy fallback: declared actions are
+  spec-shaped and never carried `enabled`).
+- **plugin-detail** — `record:quick_actions` HAD a `disabled` implementation,
+  but its `typeof === 'string'` split dropped the `{dialect:'cel', source}`
+  envelope the server compiles authored CEL into (#2661 routes envelopes to the
+  canonical formula engine), so the predicate never fired on real metadata. It
+  now feeds `toPredicateInput`'s result to `useCondition` whole, like every
+  other surface.
+
+Pinned by new `DropdownActionItem` tests (disabled-when-TRUE, false-stays-
+clickable, disabled-wins-over-enabled, boolean literal) and browser-verified
+end-to-end against the showcase `showcase_archive_task` specimen: greyed on an
+in-progress task, clickable on a done one (with `visible` hiding Mark Done on
+the same screen — the hide-vs-grey contrast).
