d2287159e0 Add nightwatch75/dns-switcher 0.1.1 (#292)
Switch the system DNS between popular providers, custom servers, or the ISP
default, from a panel on the bar — no reconnect, no captive-portal re-run.
Detection reads the active connection's own ipv4.dns/ipv4.ignore-auto-dns
instead of guessing, so a manually configured resolver (LAN ones included)
shows as its provider and DHCP-assigned DNS shows as Default (ISP). A
singleton service entry owns detection/apply so multiple bars share one
engine.

Every bar gesture (left/right/scroll) is a manifest [widget.actions] default,
resolved through noctalia's own IPC registry, so any of them can be remapped
from the bar's own gesture settings without touching the plugin. The panel
also carries a DNS lookup tester: resolve a name against the active
provider's own address with dig/nslookup, to confirm a switch took effect or
that a provider blocks a domain.

-- dns-switcher — bar widget: renders the state published by the service
-- entry (service.luau).
--
-- Click mapping is declared in plugin.toml's [widget.actions] (plugin_api >=
-- 14), not hard-coded here, so the user can remap it from the bar's own
-- gesture settings like any built-in widget:
-- Left click — panel-toggle nightwatch75/dns-switcher:panel
-- Right click — plugin nightwatch75/dns-switcher:service all apply default
-- Scroll up/down — plugin nightwatch75/dns-switcher:service all cycle next/prev
--
-- No middle-click binding: every bar widget carries a built-in `middle`
-- binding that opens its own settings, and that default is exactly what's
-- wanted here.
