Motivation

vp run loads every package's vite.config.* before it plans, so a run in one package waits for all of them, and a broken config in any package fails every run in the workspace. With every task read going through the lazy graph (#943), configs can load only when a run reaches their tasks.

Changes

• IndexedTaskGraph::load no longer loads every task and resolves every dependsOn up front. It loads the package list and the root config; another package's config loads when a run first reads its tasks, through the task query, a dependsOn or a nested vp run.
• Checks that covered the whole workspace now run when a package's config loads: cache or enablePrePostScripts outside the root config, a task named like a package.json script, a dependsOn naming a missing task, and cache settings at the top level of a task. That last error used to list every such task in the workspace; it now lists the loading package's, as the snapshot of top_level_cache_fields_workspace_error shows.
• vp run without a task lists every task, so it still loads every config.

E2E fixture unreached_package_config: packages/broken sets cache, which only the root config may set, or, in the second case, has a vite-task.json that isn't valid JSON. The first commit records today's output: every run fails with that package's error, including vt run -t build in packages/app, which only runs @test/app and @test/lib. In the second, that run succeeds, while vt run -r build and a dependsOn on @test/broken#build still fail.

Note

Medium Risk
Changes when config validation runs and which errors surface, which could hide issues until a package is first reached in a run.

Overview
vp run no longer loads every package's vite.config.* up front. IndexedTaskGraph::load now loads the package list and workspace root config only; each other package's config loads the first time a run reads that package's tasks (task selection, -r, dependsOn, or listing all tasks).

Runs scoped to one package ignore broken or invalid configs in packages the graph never touches, so startup is faster and unrelated packages can't block the run. When a run does reach a package, config errors (invalid JSON, cache outside the root, misplaced cache fields, etc.) still fail at load time as before. vp run without a task still enumerates every task, so it still loads every config.

Workspace-wide aggregation of top-level cache field errors is removed: those messages now list only tasks from the package being loaded. E2E fixture unreached_package_config documents the new behavior, and the changelog is updated.
