Merge the architecture audit refactors and follow-up UX fixes: remove release notes from generated LLM context, keep author edit controls delete-only, stabilize board refresh rendering, and address review feedback for role loading, refresh holds, moderation actions, and P2P stats polling.
* fix(thread update): refresh stale reply caches
Evict the current thread comment and known reply-page cache entries before manual refresh so stale local data does not keep replies hidden. Also defer broader multiboard suggestion feeds until the current /all time window is exhausted to reduce renderer pressure.
* fix(thread update): evict alternate reply page caches
* fix(board): hide stale time-window suggestions
* fix(thread-page): make thread auto updates opt-in
Wire `Auto` and `Update` to the same manual refresh path and cover the thread flow with an e2e harness.
* fix(thread-page): address PR review findings
* Update README.md
* fix(post): stop thread navigation from forcing OP alignment
Route-driven thread opens now use the normal top-of-page behavior, while explicit OP permalink intents carry a scrollThreadContainerCid state and resolve against the visible thread container only. The old spacer injection path is removed.
* fix(post): address PR review follow-ups
Core browsing flows around board controls, pagination, and thread pages were still largely unmeasured in the honest whole-repo report. That left route mismatches, cached-thread hydration, board action wiring, and mod-queue control regressions underprotected in CI.
