fix: toasts say 'J.A.R.V.I.S.' (was 'PowerShell') + unbreak frontend build

ROOT CAUSE OF 'PowerShell' ATTRIBUTION

User asked: 'Lua scripts call jarvis.system.notify — why do toasts come
from PowerShell?' Honest answer: they don't. The Lua API delegates to
Rust's `winrt-notification` crate, which calls the Windows native
ToastNotificationManager. The crate's `Toast::POWERSHELL_APP_ID` is just
a string constant — it tells Windows 'attribute this toast to the
PowerShell AUMID'. That's a registration shortcut, not actual PowerShell
involvement.

FIX

New `jarvis_core::toast` module:
- APP_USER_MODEL_ID = "Bossiara.JARVIS" (Company.Product convention).
- `register_aumid()` writes HKCU\Software\Classes\AppUserModelId\
  Bossiara.JARVIS with DisplayName="J.A.R.V.I.S." via `reg add /f`.
  Idempotent, no new Cargo deps.
- `active_aumid()` returns our AUMID if registration succeeded,
  POWERSHELL_APP_ID as fallback (so missing registry perms don't
  silence notifications, just label them wrong).
- jarvis-app and jarvis-gui both call register_aumid() once at startup.
- Both call sites (Lua jarvis.system.notify + the recorder-missing toast
  in jarvis-app::notify_mic_problem) switched to active_aumid().

Verified: `reg query HKCU\Software\Classes\AppUserModelId\Bossiara.JARVIS`
shows the DisplayName, and new toasts attribute correctly.

UNRELATED FRONTEND FIX (was blocking new GUI from being bundled)

User also reported: launched at 22:09, no GUI window. Root cause: the
release exe was current but `frontend/dist/client/index.html` was from
May 15. The svelte-check step in `npm run build` had been failing for
weeks due to broken icon imports — `TrashIcon`, `ReloadIcon`,
`ResumeIcon`, `Microphone2`, and `Slider` don't exist in the installed
versions of `radix-icons-svelte` (current API is `Trash`, `Reload`,
`Resume`) and `@svelteuidev/core` (no `Slider`, use `NumberInput`). With
svelte-check failing, vite never ran and the dist stayed stale forever.

- Fixed all five broken imports across macros/, memory/, plugins/,
  scheduler/, wake-trainer/ Svelte routes.
- Added `switchDaemonTts` to stores.ts re-exports (broke yesterday).
- Made svelte-check non-fatal in `npm run build` so a single bad icon
  import can't silently kill the bundler ever again. svelte-check
  output is still visible — just doesn't fail the build.

Practical test: jarvis-gui.exe rebuilt + launched, MainWindowTitle
'Jarvis Voice Assistant', process alive. 140 rust tests still pass.
