Pillow's ICO saver stores all sizes as PNG-compressed ("Vista icon"
format). PyInstaller's Windows resource-updater cannot embed
PNG-compressed entries for small sizes and silently falls back to its
default gear icon.
Fix build_icons.py to write the ICO manually: BMP DIB for sizes ≤ 128 px,
PNG only for the 256 px entry (where Windows Explorer expects PNG).
Regenerate icons/app.ico with the new code.
Also set upx=False in bcc.spec for the Windows/Linux EXE; UPX is another
known cause of icon resources being stripped from PE files.
