fix(hyprland): migrate window rules to Hyprland 0.53+ syntax
Some checks failed
Check / eval (push) Has been cancelled

Browse Source 
The default desktop showed a red Hyprland config-error banner on every
boot, occluding the Waybar. Root cause: Hyprland 0.53 rewrote window
rules — the `windowrulev2` keyword is a hard error and the old
rule-first order (`float, class:^…$`) no longer parses, so the float
rules were not applying either. Confirmed against the Hyprland 0.55.4
source (`handleWindowrule`): each comma field is now `<keyword> <value>`,
so effects carry a value and matchers take a `match:` prefix.

Migrated the 7-rule block to `float 1, match:class ^…$` form.

Verified: V0 nix flake check --no-build; built the generated
hyprland.conf; V2 theme-shot re-render — banner gone, themed Waybar
renders. Journal + MEMORY gotcha added.
