Closes the durability gap behind "grok chat returns empty replies". In a source
checkout the dashboard resolved the staged CLI tsup bundle
(packages/cli/dist/plugins/<id>/bundled.js), which resolvePluginEntryPath prefers
verbatim with no freshness check. The FN-7779 dev prebuild rebuilds each plugin's
own plugins/<id>/dist but never the staged tsup bundle, so a source-only plugin
fix ran stale until a manual `pnpm build`.
getCandidatePluginDirs now probes the live workspace source dir (<repo>/plugins/<id>)
before the staged bundle, so dev loads the freshness-checked live plugin (dist-vs-src),
self-healing even when the prebuild is skipped. The global-staged dir stays first,
so published installs (no workspace dir) are unaffected — asserted by the retained
global-install regression test plus a new source-checkout preference test.
Verified on a live dashboard: grok chat streams text and the loader now writes its
reload copies under plugins/fusion-plugin-grok-runtime/dist, not the staged bundle.
