fails to run if installed/built with go-1.22

[dropwhile]

If using go-1.22 to install:

% convergen ./internal/app/convert/convert.go
panic: runtime error: invalid memory address or nil pointer dereference [recovered]
	panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x2 addr=0x0 pc=0x103130e40]

goroutine 57 [running]:
go/types.(*Checker).handleBailout(0x14000500400, 0x14000215c38)
.....

I found a similar issue here and it looked like just updating golang.org/x/tools would be the fix.

I cloned locally, updated golang.org/x/tools, built, and it ran just fine after that.
