feat(hyprlua/columns): resizable+scrolling columns, window parking, reload-safe

Overhaul the custom "columns" Lua layout and its navigation wiring:

- Flexible sizing: per-column width weights + per-window height weights
  (Super+Alt resize), scale-to-fill when a column is underfull, scroll/pan
  when overfull. Drops the old fixed viewport/rows window heights.
- Window parking: move u/d within a column parks two windows side by side in
  one slot (persistent, split across the column axis with a divider parallel
  to the scroll direction; the column closes up so there is no gap); moving a
  parked window again pops it out past its partner.
- New windows stack into the working column (with a balance guard) instead of
  scattering, so two windows share a column/height by default.
- Cross-monitor focus/move at the column edges (relative +1/-1 selectors).
- hypr-nav: adds resize + scroll kinds; Super+wheel travels along the focused
  strip (column / tape) and falls back to workspace switch elsewhere.
- Super+Alt arrows/hjkl route resize through the layout; Super+rightclick
  auto-floats then resizes ONLY in columns (no pointer-resize hook for custom
  layouts) and is a plain resize everywhere else.
- Reload-safety: hyprctl reload dropped per-ws layout rules + Lua state,
  silently reverting columns workspaces to scrolling. init.lua now replays
  layouts-state.json (M.restore) and columns.lua re-seeds cols/rows/orient.

+-- Columns: a custom (Lua) tiling layout — a row of vertical columns. Think of it as

+-- Each column is an INDEPENDENTLY-SCROLLING vertical strip (the whole point): when a
+-- column holds more windows than fit, it pans to keep the focused one in view while the
+-- other columns stay put — like the wheels of a combination lock. Sizing is flexible,
+-- nothing is a fixed fraction:
+--   * Each COLUMN has a width weight; the viewport width is split between columns by
+--     those weights. Resizing left/right grows/shrinks the focused column.
+--   * Each WINDOW has a height weight. The base height of a weight-1 window is
+--     viewport/`rows` (rows = windows-per-view). A column that is *underfull* stretches
+--     its windows to fill (a lone window fills the column; two equal windows share it
+--     50/50) — so you can stack a file-explorer over a terminal in column 1 while
+--     Firefox owns column 2. A column that is *overfull* keeps natural heights and
+--     SCROLLS. Resizing up/down retunes the focused window's height weight.
+-- Weights and per-column pan persist across relayouts.
