fix(kon): float window sidebar, transcription doubling guard, branding

Float window fixes:
- Root layout now detects /float and /viewer URLs and hides Sidebar,
  Titlebar, TaskSidebar for secondary windows. Belt-and-braces fix
  since +layout@.svelte should handle this but may not in SPA mode.
- Float window title: "Ramble - To-do" → "Kon - To-do"

Transcription doubling guard:
- Added chunk_id deduplication set in DictationPage — if a chunk_id
  has already been processed, skip the duplicate result
- Set cleared on each new recording session
