Fix integration papercuts found in cross-source review

getAtomDetails's gtasks case was a stub returning a hardcoded "Google
Task" title, so every gtask completed via the web Tasks/Timeline tab
or the Agent API logged into completed-tasks history with no real
title or due date -- now calls findGoogleTask like every other gtasks
call site already does. Gtasks completion also skipped cache
invalidation in two call sites (HandleCompleteAtom, the Agent API's
handleAgentTaskToggle) that already had it for trello; both now
invalidate CacheKeyGoogleTasks the same way the widget handlers do.
HandleTaskDetailPage (the widget deep-link fallback page) hand
-duplicated loadTaskDetailData's lookup instead of calling it, so it
never got this session's earlier gtasks-detail fix -- now delegates.
Also deleted PlanToEatAPI.GetRecipes, dead code since its introduction
("for Phase 2," never called).

Adds a running .agent/critiques.md tracking structural/process
critiques surfaced in conversation, separate from a concrete plan.
