  "message": "Propagate module dependencies transitively via public_deps\n\nWhen using C++ modules, dependencies must be treated as transitive. If a\ntarget `A` has a `public_deps` on module `B`, and `B` in turn has a\n`public_deps` on module `C`, any target that depends on `A` must also be\nprovided with the dependency on `C`.\n\nPreviously, GN did not propagate these module dependencies recursively.\nThis meant the dependency on `C` was not passed to `A`\u0027s dependents,\nwhich could lead to compilation failures. This behavior is incorrect, as\ndependencies between C++ modules are analogous to transitive header\ninclusions.\n\nThis change fixes this by recursively traversing the `public_deps` graph\nin `ResolvedTargetData` to collect the complete set of transitive module\ndependencies. This ensures that all module dependencies are correctly\npassed to the compiler.\n\nBug: 40440396\nChange-Id: Ib7b0e09477705708c92e6981b651c0eb9d6617e3\nReviewed-on: https://gn-review.googlesource.com/c/gn/+/19100\nReviewed-by: David Turner \u003cdigit@google.com\u003e\nCommit-Queue: Takuto Ikuta \u003ctikuta@google.com\u003e\n",
