v1.1.1 save folder

[1.1.1] — 2026-09-05

Added

• A place to say where recordings go. Choose folder sits next to Open
  folder under Sessions and opens a small dialog: the folder itself at the
  top, then a checkbox for one folder per month and one for the recording type
  in the file name, with a live example of what a new file will be called. An
  external drive or a synced folder was possible before only by moving the
  whole data directory with DREAM_VOICETRAINING_HOME, which took the settings
  along with it.
• A button that moves what is already there. At the bottom of the same
  dialog: existing recordings are moved into the chosen folder and renamed to
  the chosen scheme. Names given by hand are kept, a file of the same name at
  the destination is never overwritten, and files that cannot be found are
  reported instead of dropped from the list. The setting is only stored once
  the files have actually arrived.
• Recordings can now live in subfolders. sessions.json stores the name
  relative to the recording folder with forward slashes, so the list stays
  usable across systems, and it stays in the program data itself — a list that
  travels with the WAV files onto an external drive is gone the moment the
  drive is not plugged in. Recordings left behind at the old location are still
  found and played.
• The type in the file name uses a fixed English short form — reading, hum,
  vowel-a, vowel-i, vowel-u, free — so switching the interface language
  does not rename anything.
