fix(acr): enumeratePlugins honors enabledPlugins + polyrepo cache installPaths (M-BUG-1)

active-config-reader walked ~/.claude/plugins/marketplaces and ignored both the
enabledPlugins toggle and the polyrepo cache layout. On a polyrepo machine it
counted disabled/uninstalled marketplaces plugins as "active" while MISSING the
actually-enabled plugins installed under plugins/cache. This corrupted the agent
listing and every pluginList consumer (manifest, AGT, whats-active, hooks, rules).

Now: when installed_plugins.json is present, inject only plugins that are in the
manifest AND enabledPlugins[key]===true, each resolved to its active installPath
(incl. cache/). When the manifest is absent (fixtures/pre-v2 installs), fall back
to the historic marketplaces walk rather than silently dropping config — mirrors
file-discovery.mjs's "trust installed_plugins.json" contract.

Verified on real machine: agent listing 114->104, ghost plugins (newsletter,
content-machine, harness, kiur, ...) gone, voyage/linkedin/ms-ai/okr now correctly
counted. Full suite 1301/0; byte-stable snapshots untouched (hermetic empty HOME).
