Plugin "${pluginId}" is not installed in project scope

Error message

Plugin "${pluginId}" is not installed in project scope

What it means

MarketplaceManager.uninstallPlugin() resolves which registry (user-level or project-level) holds the plugin before removing it. This error is thrown when the caller explicitly passed scope="project", but the plugin id was only found in the user-scope installed-plugins registry, so uninstalling from project scope is impossible. It prevents silently modifying the wrong registry or removing a plugin that is not actually installed where the user asked.

Solutions

1. Re-run without the --scope flag so the manager auto-targets the scope where the plugin is actually installed.
2. Re-run with `--scope user` to uninstall from the user registry where the plugin is actually recorded.
3. Verify where the plugin is installed with `omp plugin list` (it shows per-scope entries) before specifying a scope.

Example fix

// before
await manager.uninstallPlugin("formatter@team", "project");
// after
await manager.uninstallPlugin("formatter@team", "user"); // or omit scope to auto-resolve

import { MarketplaceManager } from "./manager";
const installed = await manager.listInstalledPlugins();
const entry = installed.find(p => p.id === pluginId);
if (!entry) throw new Error(`Plugin ${pluginId} is not installed`);
if (scope === "project" && entry.scope !== "project") {
  scope = entry.scope; // retarget to the scope where it actually lives
}

function isInScope(entry: { id: string; scope: "user" | "project" } | undefined, scope: "user" | "project"): entry is { id: string; scope: "user" | "project" } {
  return entry !== undefined && entry.scope === scope;
}

try {
  await manager.uninstallPlugin(pluginId, "project");
} catch (err) {
  if (err instanceof Error && err.message.includes('is not installed in project scope')) {
    await manager.uninstallPlugin(pluginId); // let the manager resolve the scope
  } else throw err;
}

When it happens

Trigger: Calling `uninstallPlugin(pluginId, "project")` (or the equivalent `omp plugin uninstall <id> --scope project` CLI path) when `#findInBothRegistries(pluginId)` returns projectEntries empty/undefined but userEntries non-empty.

Common situations: The plugin was installed with `plugin install --scope user` (the default for personal setups) but the uninstall command repeats `--scope project` copied from a teammate or CI script; the project-local registry file (e.g. .omp/plugins in the repo) was deleted or the command is run outside the project directory, so only the user registry still lists the plugin.
