## What
Fix `RECORD_SELECTION` items leaking into the command menu when nothing
is selected, and unify how the menu renders in normal vs edit mode.
## The bug
`RECORD_SELECTION`-availability items were showing up even when
`numberOfSelectedRecords === 0`. New util
`doesCommandMenuItemMatchSelectionState` gates them, applied
consistently in the runtime provider and the editor.
## The refactor
`PinnedCommandMenuItemButtonsEditMode` was a 140-line near-duplicate of
`PinnedCommandMenuItemButtons` with its own (drifting) filter logic.
Killed it. Edit mode now flows through the same
`CommandMenuContextProvider` with a new `isInPreviewMode` flag — one
filter chain, one rendering path.
## Behavior in edit mode
**Header (pinned buttons in page header):**
- Runs the full filter chain — object metadata, page type, selection
state, page layout, *and the conditional availability expression*
- Buttons render at full styling but are inert via `pointer-events:
none` + `cursor: not-allowed`
- Preview now reflects exactly what users will see on the live page (not
a grayed-out approximation)
**Side panel editor:**
- New `useEditableCommandMenuItems` hook
- Same filters as runtime *minus* the conditional availability
expression and `FALLBACK` items — so it surfaces everything that's
actually configurable for this page context
- Still gates on selection state — if no records selected,
`RECORD_SELECTION` items are hidden from the editor too. Open to
feedback if we'd rather always show them so users can pin them ahead of
time.
## Misc
- `usePinnedCommandMenuItemsInlineLayout` — visible count now waits
until every item is measured before committing. Fixes a flash of wrong
counts on mount/resize
- Renamed `useCommandMenuContextApi` → `useCurrentCommandMenuContextApi`
— name now conveys it reads from the *current* scoped context store
- Copy: "Records selected" → "Record(s) selected"
