Hammerspoon's menubar icon position not properly handled

[kassi]

Hammerspoon always places its icon and the icons created with hs.menubar to the leftmost position, regardless to which position I move it.
It should be handled correctly and place it to the same position.

Problem: I'm using Thaw to manage the menubar and since Hammerspoon doesn't treat the position right and places the icons to the leftmost position, they are always moved to hidden section. This is not a Thaw problem, but a problem how Hammerspoon handles menu bar icon position.
Without Thaw, when I move the icon with CMD+Drag around, close Hammerspoon and reopen it again, it should appear at the same position, but it doesn't. Apps like Thaw (or Ice beforehand) need the position to be handled properly.

This is a similar problem as with the stats app which got fixed (see stonerl/Thaw#190 (comment)).

This is likely fixable by setting autosaveName on the hs.menubar items. The autosaveName parameter (added in PR #3195 / available since 0.9.98) gives macOS a stable identifier to persist the item's position across destroy/recreate cycles.

Without it, macOS treats every recreated NSStatusItem as brand-new and places it at the far left — which is why menubar managers (Thaw, Ice, Bartender, etc.) lose track of it.

For Spoon authors: pass a name as the second argument to hs.menubar.new():

-- Before
self.menuBarItem = hs.menubar.new()
-- After
self.menuBarItem = hs.menubar.new(true, "MySpoonName")

I've submitted Hammerspoon/Spoons#362 to fix all 14 affected Spoons in the official repo, and #3864 proposing that hs.menubar.new() auto-generate an autosaveName when none is provided, so existing code benefits without changes.
