-- Enter focus mode — three side-effects bundled into one voice trigger:
--   1. activate "work" profile (silences fun/games/banter commands)
--   2. enable Windows Focus Assist (Quiet Hours) via registry tweak
--   3. schedule a "стретчинг" reminder in 50 minutes via the persistent scheduler
--
-- All three are independent — if one fails, the rest still happen.

-- 2) Windows Focus Assist: writes the registry key Windows uses for
--    "Priority only" mode. This is the same key Windows 11 toggles when you
--    flip Focus on/off via the Action Center.
