Follow-up to the previous commit addressing the Plugin Store browse path specifically. Most users install plugins via the store (ZIP extraction, no .git directory) so the git-info mtime cache from the previous commit was a no-op for them; their pain was coming from /plugins/store/list. Root cause. search_plugins() enriched each returned plugin with three serial GitHub fetches: _get_github_repo_info (repo API), _get_latest_commit_info (commits API), _fetch_manifest_from_github (raw.githubusercontent.com). Fifteen plugins × three requests × serial HTTP = 30–45 sequential round trips on every cold browse. On a Pi4 over WiFi that translated directly into the "connecting to display" hang users reported. The commit and manifest caches had a 5-minute TTL, so even a brief absence re-paid the full cost. Changes. - ``search_plugins``: fan out per-plugin enrichment through a ``ThreadPoolExecutor`` (max 10 workers, stays well under unauthenticated GitHub rate limits). Apply category/tag/query filters before enrichment so we never waste requests on plugins that will be filtered out. ``executor.map`` preserves input order, which the UI depends on. - ``commit_cache_timeout`` and ``manifest_cache_timeout``: 5 min → 30 min. Keeps the cache warm across a realistic session while still picking up upstream updates in a reasonable window. - ``_get_github_repo_info`` and ``_get_latest_commit_info``: stale-on-error fallback. On a network failure or a 403 we now prefer a previously- cached value over the zero-default, matching the pattern already in ``fetch_registry``. Flaky Pi WiFi no longer causes star counts to flip to 0 and commit info to disappear. Tests (5 new in test_store_manager_caches.py). - ``test_results_preserve_registry_order`` — the parallel map must still return plugins in input order. - ``test_filters_applied_before_enrichment`` — category/tag/query filters run first so we don't waste HTTP calls. - ``test_enrichment_runs_concurrently`` — peak-concurrency check plus a wall-time bound that would fail if the code regressed to serial. - ``test_repo_info_stale_on_network_error`` — repo info falls back to stale cache on RequestException. - ``test_commit_info_stale_on_network_error`` — commit info falls back to stale cache on RequestException. All 29 tests (16 reconciliation, 13 store_manager caches) pass. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
