Merge remote-tracking branch 'origin/feat/quickshell-dense-bar' into feat/quickshell-dense-bar

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.

+Quickshell hot-reloads QML on file save when already running, so for most edits just save and check the running instance rather than restarting `qs`. It watches file CONTENT: `touch` alone never reloads (mtime is not a change), while any real edit does, including inode-replacing ones (`sed -i`, `perl -i`). A save that is not picked up leaves the shell rendering the previous config with no error — `qs log` shows a `Reloading configuration...` line for every save it saw, so that is the check.
