@coderabbitai Please suggest a fix for this issue and supply a prompt for an AI coding agent to enable it to apply the fix. Include the file and symbol names indicated in the issue at the head of your response. Ensure that this is validated against the current version of the codegraph. If further refinement to address this finding would be deleterious, please supply a clear explanatory one to two paragraph markdown message in a code block that I can paste into the CodeScene web ui's diagnostic suppression function so this diagnostic can be silenced. tests/runner_cases/default_targets.rs Comment on lines +207 to +285 fn real_ninja_treats_option_like_targets_as_operands() -> Result<()> {

Insert Ninja's operand terminator only when a build request has targets. This preserves the no-target command shape while preventing configured and explicit target names from changing Ninja's option parsing. Cover single, multi-target, and no-target argv ordering at the command construction boundary.
Exercise the shared build path with configured and explicit option-like targets, then use a real Ninja workspace to prove a sibling directory and its build file are not selected.
Record the build-target terminator decision, including the rejected leading-hyphen restriction, and link the design and documentation index to the new ADR.

Summary
This change inserts Ninja’s
--operand terminator between Netsuke-ownedoptions and each selected build target. Configured and explicit target strings
can no longer change Ninja’s control plane.
Closes #645.
