## Parse-checks Godot scripts the way the game loads them.
##
## Usage, from the project root, after `godot --headless --path . --import`
## (which builds the class cache that `class_name` lookups need):
##
##   godot --headless --path . -s res://.claude/scripts/godot-parse-check.gd -- res://src/a.gd res://src/b.gd
##
## Prints `ok: <path>` or `PARSE FAIL: <path>` per script, with Godot's own
## error lines above each failure. Exit 0 when every script loads, 1 when any
## does not, 2 when no script was given.
##
## Why not `--check-only`: it compiles the file with no autoloads
## registered, so valid code that names an autoload exits 1 with
## "Identifier not found". Loading in `_initialize()` runs after startup has
## registered them; `_init()` runs before, and fails the same way.
