v0.3.3

### Fixed
- **Settings → About showed the wrong architecture in the Docker/web build.**
  The "Architecture" row rendered the *client browser's* platform
  (`navigator.platform` → e.g. "Win32"); it now reports the **server's** CPU
  architecture from the backend (`platform.machine()`), correct for both the
  desktop app and Docker. The blank version/GPU/RAM/VRAM in the same report
  were the loopback-gate 403s already fixed in v0.3.2. (#262)

### CI
- The release SHA-256 checksum step no longer uses `mapfile` (a bash 4+
  builtin) — it broke on the macOS runner's bash 3.2 and dropped the macOS
  `SHA256SUMS` for v0.3.1/v0.3.2. Now portable to bash 3.2.
