chore(terra): unload hypr-chrome, round corners at 25

Comments out both the plugin and its `plugin.hyprchrome` settings — Hyprland
rejects plugin config for a plugin that is not loaded, so the two have to go
together. The flake input stays, so re-enabling is two uncommented lines.

With the window frames gone, decoration rounding goes 10 -> 25 and
rounding_power 2.0 -> 1.0 (previously unset). Both were applied live first via
`hyprctl eval 'hl.config{...}'`; plain `hyprctl keyword` is refused by the lua
config's non-legacy parser.
