v0.77.0

What's Changed

• evals: #919 -- still-valid past runs pool as evidence; late criteria disclosed, never data age; bundle shape 62 by @brookstalley in #931
• evals: the paid lane hands the writer a campaign bundle, and its broken contract drops the memo's summary by @brookstalley in #933
• evals: a run that recorded no template digest or served model is never pooled by assumption by @brookstalley in #934
• evals: the chi-square node and t-critical caches are bounded by @brookstalley in #936
• Release 0.77.0: peer wait backoff, tier read counts, background run ids, MCP host apps, evals resume by @pacepace in #937
• testament image: arm64 runners build indexed-zstd from source, and it imports by @brookstalley in #927
• mcp: a host app serves MCP on its own app, with tool metadata, structured tool errors and a live tool set by @brookstalley in #929
• evals: resume an interrupted run, sweep or launch as the same run (#918), and a row no worse than the margin (#916) by @brookstalley in #922
• Release v0.77.0 by @pacepace in #938
