feat(quickshell): add HyprChromeShell, workspaces panel, persistent backdrop

Browse Source 
HyprChromeShell owns what the rail's surfaces have to agree on: the target
screen, the density and the shortcut that toggles it, and the bar/backdrop
layer PAIR. That pair is why the wrapper exists — the backdrop has to sit
exactly one layer below the bar in both densities, and split across two
files the two assignments drifted apart and put the scrim over the bar.
HyprChromeBar is now just its own surface; ChromeBackdrop takes its layer.

The backdrop renders in both densities instead of fading out: full-screen
while expanded, scoped to the band the rail occupies while collapsed, with
a proportional tail fading off the bottom of that band. Both gradients end
on their solid color when there is no fade — with a zero-length ramp the
start and end stops coincide, Qt sorts stops unstably, and the transparent
one winning turned "no fade" into a ramp across the whole scrim.

WorkspacesPanel, between host and vitals, shows the active workspace per
monitor: one accent box per output collapsed, the full strip with the shown
one filled expanded, lined up in a column behind a fixed-width name cell.

// Which workspace each monitor is currently showing, in the hyprchrome panel
// chrome, in both of BarPanel's densities.
//
// One indicator in both: a box carrying the workspace's name, filled accent
// while its monitor is showing it and outlined otherwise. Collapsed, each
// output gets exactly one — the workspace it is on. Expanded, it gets the whole
// strip it cycles through, at a larger cell, with the shown one filled.
//
// Expanded, the strips line up in a column: the output name sits in a
// fixed-width cell, so the boxes start at the same x on every line regardless
// of how long a connector name is.
//
// Both densities read the same two models, so they cannot disagree. Hyprland's
// own distinction is kept: `active` is the workspace its monitor is showing
// (one per output), `focused` is the single one taking input — so the fill
// marks the shown workspace and the accent marker marks where the keyboard is.
//
// Display only: workspaces expose activate(), but BarPanel's density toggle
// covers the whole panel, so a chip could not receive the click anyway.
