Subject: [PATCH 01/56] cloud sidebar: hide link tabs while a machine connects,
 line its connecting row up with new workspace, hover on the ports action

- while a machine connects, ports, terminals and displays have nothing current, so the tab row keeps only resources (fleet telemetry)
- the connecting spinner takes new workspace's chevron column
- the ports status action (refresh, set up vpn) is a quiet rounded chip with the tree's fills; its title brightens and fill deepens on hover and press

Subject: [PATCH 05/56] cloud sidebar: continuous machine and tab reorder,
 refresh icons in the section headers

machine drags under the cloud machines section were refused because the
drop only looked at top-level rows; drops and menu moves now find the
machines wherever they sit.

the real machine row is the drag visual: open machines close for the
drag, peers spring aside against frozen geometry, and the drop lands
every row from where it is on screen. mode tabs drag the same way and
hand off to a native drag when pulled out of the bar, so they still open
as panes. switching tabs slides one selection highlight, and an icon-only
tab centers its icon. refresh moves from the bottom of the panel to the
cloud machines and my devices headers.

Subject: [PATCH 06/56] move the header refresh icons and tab switch highlight
 to the follow-up pr

keeps this pr to machine and tab reorder. the refresh icons in the
cloud machines and my devices headers, the sliding tab highlight and the
centered tab icons come back in the stacked cloud sidebar polish pr.

Subject: [PATCH 07/56] cloud sidebar: refresh icons in the section headers,
 sliding tab highlight, centered tab icons

refresh moves from the bottom of the cloud panel to an icon left of the
cloud machines + and the my devices menu, with the same hover and a
spinner that stays on screen while it runs. switching tabs slides one
selection highlight while the widths re-share, and an icon-only tab
centers its icon.

Subject: [PATCH 08/56] machine lift: closing machines above the held one is
 not a move

review findings on the lift:
- closing open machines above the source moved its row up, and that
  shift counted as pointer travel, so a small nudge could move the
  machine several slots. only the pointer's travel picks the slot now;
  the held row glides from under the hand into its closed slot
- a drag whose end is never reported cancels once the button has been
  up for a moment, instead of following the pointer until the next click
- the release lays out before landing, so the rows glide instead of snapping
- mode bar: a late gesture change after the release no longer starts a
  phantom drag, and tab frames are measured without the drag offset
- tests: the lifted drop gets a proposal that disagrees with the lift, and
  a new test opens machines above the held one

Subject: [PATCH 09/56] cloud sidebar polish: ports alignment, empty states,
 pane button, full tab names, smoother switching and resize, upgrade at the
 limit

- ports tab: the status text and its button start on the ports tab's edge
- an empty fleet keeps a "No cloud machines yet" line, so cloud machines
  keeps its chevron; my devices says "No other devices yet"
- the open-as-pane button stays in the bar in every tab; a tab that can't
  open as a pane says so in its tooltip
- the right sidebar's minimum (and opening) width follows the mode tabs
  shown, so every tab name fits with the trailing buttons
- switching tabs moves one highlight with no crossfade, and row
  selection is a layer so it no longer flickers while the sidebar resizes
- a failed create keeps its warning icon on the name's line
- a create refused at the plan's machine limit offers Upgrade Plan when a
  bigger plan exists
- the cloud machines refresh icon spins only for a refresh someone asked for

Subject: [PATCH 10/56] right sidebar width fits the selected tab's name with
 the others as icons; ports layout back as it was

the minimum and opening width now leave room for one full tab name (the
widest, so it doesn't change as the selection moves) with every other
tab at its icon, instead of every name in full. the ports tab's status
alignment goes back to main's.

Subject: [PATCH 11/56] cloud sidebar: refresh icons sit after the section
 counts; a failed create keeps its status readable

the cloud machines and my devices refresh icons move from the header's
trailing buttons to right after the title and count, small and in the
count's grey. the header passes clicks through to the row everywhere but
the icon, so clicking the header still opens and closes the section.

in a narrow sidebar a failed create's name gives way before its status.

Subject: [PATCH 13/56] cloud sidebar: refresh icon hover fill, a quieter tab
 switch, "Discover other devices"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- the section headers' refresh icons take the same hover fill as + and
  ⋯; their resting color and size are unchanged
- switching tabs no longer moves a highlight across the bar. the widths
  ease on one short curve with no overshoot, the old tab's fill fades as
  it narrows and the new one's as it opens, labels are uncovered by their
  slot (with a soft edge) instead of re-truncating every frame, and an
  icon-only tab's icon glides to its leading spot
- my devices and settings say "Discover other devices" (and "Stop
  discovering other devices"), in all 9 locales

Subject: [PATCH 16/56] cloud sidebar: clicking a header's refresh icon
 refreshes instead of toggling the section

each reload of a section header cleared the icon's clickable spot, and
SwiftUI reports the icon's frame only when it moves, so after the first
reload the click fell through to the row and opened or closed the
section. a header now keeps the spot across reloads; it clears only when
the cell is reused for another kind of row.
