Select: Select All skips hidden isolated groups, and menu commands stay within what it selects

Select All, All on Active Artboard and Inverse select from selectable:
the visible, unlocked objects on visible, unlocked, non-template
layers and sublayers, or in isolation mode the visible, unlocked
objects in the isolated group or layer and in its visible, unlocked,
non-template sublayers. Other Select menu commands did not use it:

- Clipping Masks, All Text Objects, Stray Points and Open Paths
  selected hidden and locked objects and the objects in hidden or
  locked groups and sublayers.
- Point Text Objects, Area Text Objects, Brush Strokes, Bristle Brush
  Strokes and the Same commands for symbols, fonts and text colors
  checked an object's own flags and its layer's, but not those of the
  groups and sublayers between them.
- Next Object Above and Below selected the object beside the selected
  one even when it was hidden, locked or a sublayer.
- A saved selection picked from the Select menu selected again the
  objects hidden or locked since it was saved.
- Direction Handles direct-selected the hidden and locked paths in a
  selected group.
- In isolation mode, the commands in the first two bullets, the other
  Same commands, All on Same Layers and a recalled saved selection
  selected art outside the isolated group or layer. Next Object Above
  and Below and Direction Handles did so only when the selection
  already held something that was not inside the isolated group or
  layer.

In isolation mode selectable checked the flags of the isolated group's
or layer's objects and sublayers, but not those of the group or layer
itself or of the groups and layers it is in. Select All, All on Active
Artboard and Inverse still selected the isolated group's or layer's
objects after it, or a group or layer it is in, was hidden or locked.

In isolation mode selectable now returns nothing while the isolated
group or layer, or a group or layer it is in, is hidden, locked or a
template layer. walk_selectable visits the objects selectable returns
and the objects inside them, leaving out hidden and locked objects
with what they hold. It visits nothing in a hidden, locked or template
layer, sublayer or group. The commands in the bullets above now select
from it. All on Same Layers takes the objects on the selected objects'
layers that selectable returns. Next Object Above and Below pass over
the objects walk_selectable leaves out, and leave the selection as it
is when none is left in that direction.

The params texts of Direction Handles and Recall Selection,
docs/mcp.md (Object selection, Saved selections) and one line in the
evidence list of docs/target-app-parity.md describe the change.

 ## Saved selections
 
 Select → Save Selection… keeps the selected objects under a name, in the document: `select.save {name?}` (default
 the first free "Selection N"; an existing name is replaced with the current selection; at most 25 per document,
 names up to 255 characters) → `{name}`, one undo step. `select.savedList` lists the names in menu order, and

+`select.recall {name}` selects those objects again, except the ones deleted since and the ones hidden, locked or

 renames and deletes: `select.editSaved {name, newName?, delete?}`, or several at once as
 `{edits: [{name, newName?, delete?}…]}` in one undo step, where every `name` is the name before the edit and the
 names must stay unique. In the desktop app the saved selections are listed at the bottom of the Select menu
