feat(hyprlua/orbit-menu): sci-fi zoom navigation + holographic overlay + opening intro 

Replaces the plain Gtk.Stack crossfade with a focal-point zoom (Gtk.Fixed +
Gsk.Transform): the clicked node's screen position becomes a pivot the parent
page zooms into while the child page slides in from that exact spot and grows
to become the new center — like a moon becoming the planet you now orbit.
Going back reverses the same motion around the same remembered point
(_stack_origins tracks it per depth).

Adds a holographic overlay (config.json "hologram" toggle, default on):
violet scanlines + a looping sweep band + magenta/red noise specs with real
per-particle lifetimes (fade in/out, not single-frame flicker), all composited
through a radial mask so it reads as one soft-edged glow over the menu rather
than tinting the whole square canvas.

Adds an opening-only intro (never plays between nodes): each button starts
invisible and fades in on a staggered cascade — center first, then ring nodes
in order — with a bright noise burst flashing at each node's position the
instant it starts appearing, like it's condensing out of the static.

Also fixes a transparency regression: the new hologram DrawingArea sits above
everything via Gtk.Overlay, and the cyberqueer theme's aggressive `*` selector
was painting it an opaque background, hiding the whole menu — forced
transparent via CSS, same fix pattern as the earlier orbit-node label bug.

same base element recursively applied, so orbits nest arbitrarily deep. Clicking the
center (or Backspace) steps back out one level; Escape closes the menu.
Each level is rendered once into its own Gtk.Fixed page and cached in a Gtk.Stack
keyed by the path of indices taken to reach it (e.g. (2, 0)); navigating in either
direction just swaps the stack's visible child, and the Stack's own CROSSFADE
transition gives the nested navigation a smooth fade instead of a hard cut. A
category with a dynamic child list (open windows, user scripts) passes
`dynamic=True` so its page is rebuilt — never cached — on every visit.
Each level is rendered once into its own Gtk.Fixed page and cached in a plain dict
keyed by the path of indices taken to reach it (e.g. (2, 0)). Navigating between
levels plays a sci-fi-orbital-map zoom (see _start_transition/_update_transition):
the clicked node's on-screen position becomes a focal point — the parent page
zooms *into* that fixed point (as if diving toward it, everything else rushing off
past the edges) while the child page slides in from that exact spot and grows from
a small dot up to the full view, becoming the new center, like a moon becoming the
planet you now orbit. Going back plays the same motion in reverse around the same
point (each depth's focal point is remembered in _stack_origins). Driven by the
same per-frame tick callback that animates the satellites, using GTK4's
Gsk.Transform (via Gtk.Fixed.set_child_transform) to scale each page around an
arbitrary pivot. A category with a dynamic child list (open windows, user scripts)
passes `dynamic=True` so its page is rebuilt — never cached — on every visit.
Ported from the ~/code.dev/test-astralmenu prototype onto raw Gtk4LayerShell (no
Astal.Window dependency) to match astal-menu/window.py's layer-shell approach.
