refactor(ffi-linkage): Phase 9.2d — rename foreign_path → runtime_path (coupled .sx↔.zig↔hook)

The JNI/runtime-class path (Decision 5, Runtime* family). Coordinated across the hook boundary so the BuildOptions accessor + its registered hook string stay in sync: - src/: RuntimeClassDecl.foreign_path→runtime_path, splitForeignPath→splitRuntimePath, foreignPathToJavaName→runtimePathToJavaName, jni_main_foreign_paths→ jni_main_runtime_paths, hookJniMainForeignPathAt→hookJniMainRuntimePathAt, and the hook string 'BuildOptions.jni_main_foreign_path_at'→'…runtime_path_at'. - library/: build.sx accessor jni_main_foreign_path_at→jni_main_runtime_path_at + bundle.sx call sites + the local var → runtime_path + a comment. - specs.md: the accessor name + <foreign_path_with_dots> doc refs. - Regenerated 37 .ir snapshots: every program importing build declares the renamed @BuildOptions.jni_main_runtime_path_at hook stub — symbol-name change only (verified the .ir diff is ONLY this rename; reverted orthogonal empty-file normalization). Suite green (646 corpus / 444 unit, 0 failed).
