Don't add defender exclusion by default

[Hades32]

Adding exclusions to an anti-virus is opening the system to new attack vectors, especially when it's a guessable/well-known location which is user-writable.

Therefore, it should be possible (as a developer) to completely remove this option, or even better to remove it by default and add an explicit toggle to enable it with some note, that this is a potentially risky thing to do

dev-cli/src/commands/pack/win.ts

Lines 75 to 77 in 402e9cc

	Section "Add %LOCALAPPDATA%\\${config.dirname} to Windows Defender exclusions (highly recommended for performance!)"
	ExecShell "" '"$0"' "/C powershell -ExecutionPolicy Bypass -Command $\\"& {Add-MpPreference -ExclusionPath $\\"$LOCALAPPDATA\\${config.dirname}$\\"}$\\" -FFFeatureOff" SW_HIDE
	SectionEnd
