Stack Dependencies Autoinclude Values

stack-dependencies: autoinclude blocks can reference values.*

An autoinclude block may now reference the stack's values.*. Previously a values.* reference was rejected at stack generate time, except in a dependency config_path. It now resolves to a literal like local.*, unit.<name>.path, and stack.<name>.path, wherever it appears: inputs, generate, remote_state, mock_outputs, and config_path.

Function calls in an autoinclude now resolve at generate time too, in the terragrunt.stack.hcl context, instead of being kept verbatim and evaluated in the generated unit. Only a dependency.* reference (a dependency's outputs) stays verbatim and resolves inside the unit; in a mixed expression the stack-level parts resolve and only the dependency.* reference is kept.

Because functions now evaluate against the stack file rather than the unit, directory and include functions report the stack file's location: get_terragrunt_dir returns the stack file's directory, and path_relative_to_include returns ".". If you relied on these resolving in the unit, move them to the unit's own configuration, or derive a per-unit value such as a remote_state backend key from unit.<name>.path.

A locals block inside an autoinclude remains rejected; declare stack-level locals in terragrunt.stack.hcl instead.
