* 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.
