Taskfiles

Similar to shell scripts and functions, but potentially lesser OS dependencies (has an embedded sh interpreter in the single Go binary task) and easy to have directory/project-specific tasks/aliases/functions.

{{.var}} replaces sh/bash ${var} for Task-managed variables (within cmds, ${var} can sometimes still be used for shell-managed variables depending on how it's done)

Pairs well with: yq, envsubst, and other CLI tools.
