Let plugins switch profiles (add a switch-profile command to the plugin API)

anilr

Request: please add a plugin API to switch the active profile. Right now a plugin can change a key's icon but has no way to change profiles, and that one gap blocks a whole class of plugins.

My use case: a single button that acts like a smarter auto-switch. It shows the icon of whatever app is focused (open Zoom → Zoom icon) and, when pressed, switches the deck to that app's profile. A plugin can already detect the focused app and update the icon — it just can't do the switch.

As far as I can tell there's no command for it (the manifest has a Profiles field, but nothing at runtime to actually switch). Three things would fully enable this:

• Switch profile/page — a command to switch to any user profile by name or UUID (not only plugin-bundled ones).
• Read the current profile — so a plugin can tell where it already is.
• Nice-to-have: a "focused app changed" event — so plugins don't have to poll the OS.
  

Even just #1 and #2 would make this possible. Thanks!
