DCT-OS 1.2.6

Changed

• The database now lives in a per-user folder. DCT-OS keeps its database in
  your per-user application folder (e.g. %LOCALAPPDATA%\DCT-OS on Windows)
  rather than the folder it happens to be launched from — so it can't end up in a
  synced (OneDrive) or protected location where writes are silently blocked. An
  existing database in the launch folder is picked up automatically and kept.

Added

• A clear message when the database can't be saved. If antivirus or ransomware
  protection (e.g. Bitdefender, Windows Controlled Folder Access) or a read-only
  folder is blocking DCT-OS, startup now says so — and how to fix it (allow-list
  DCT-OS, or set DCT_DATA_DIR to a writable folder) — instead of failing silently
  the first time you try to create a project.
• A first-run summary on launch showing where your data is stored and the
  address to open DCT-OS.
