The claude-plugins provider read installed_plugins.json but never the
`enabledPlugins` map Claude Code keeps in ~/.claude/settings.json and
<project>/.claude/settings(.local).json. Two consequences: a plugin the
user switched off for a project still loaded there, and a local-scope
install enabled for a project never loaded unless the project directory
matched the install's recorded projectPath exactly.
Merge enabledPlugins across the same layers Claude Code consults (user
settings, then the active project root's and cwd's .claude/settings.json
and settings.local.json; later wins) and apply it in
listClaudePluginRoots: `false` hides the plugin, `true` opts a
local-scope install in regardless of projectPath. Untouched ids keep the
existing behavior. Contributing settings files join the cache key.
Solves: Claude marketplace plugins loading in the wrong projects
Tests: claude-plugins.test.ts — per-project off switch (local wins over
settings.json, other projects unaffected) and enabledPlugins:true
opt-in for a local install recorded under a parent directory
