fresh-editor 0.3.2

//! End-to-end coverage for the dev-container *attach* flow against
//! the in-tree fake CLI ([`scripts/fake-devcontainer/`]).
//!
//! Drives Flow A from `docs/internal/FAKE_DEVCONTAINER_TEST_PLAN.md`:
//! launch the editor in a workspace with a `.devcontainer/devcontainer.json`,
//! accept the "Reopen in Container?" popup, and assert that the
//! container authority lands.
//!
//! No Docker daemon, no Node, no `@devcontainers/cli` install — the
//! harness's [`with_fake_devcontainer`] helper points the editor at
//! the bash shims that ship in-tree and an isolated state directory.
//!
//! Asserts go through the editor's public state surface
//! (`Authority::display_label`, on-disk state files, plugin global
//! state) — never internal popup state — per CONTRIBUTING.md §2.
//!

/// `plugin_global_state` blob that the workspace serializer writes
/// to disk on quit and reads back on relaunch.
///
/// The plugin writes the decision in `devcontainer_on_attach_popup`
/// before kicking off `runDevcontainerUp`, so by the time the
/// container authority lands the key must be visible in the
/// captured state. If this test ever starts failing, the regression
/// is in either the plugin's call ordering (pre-`setAuthority`) or
/// in how `capture_workspace` snapshots `plugin_global_state` — the
/// production cold-restart bug from the test plan would surface
