devkit avs call fails.

devkit avs call --signature="(uint256,string)" args='(5,"hello")'

Incorrect Usage: flag provided but not defined: -signature

2025/07/16 14:04:58 flag provided but not defined: -signature

Also the autocomplete on zsh seems broken. When I type devkit avs call --sig and press tab, I get

devkit avs call --sigpanic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x2 addr=0x30 pc=0x10501b3b8]

Start at cmd/devkit/main.go around line 63 and reproduce the reported avs call and zsh completion command. Trace the avs call command registration and the completion path shown in the urfave/cli stack trace; done means the signature option is handled and pressing tab after --sig no longer panics.
