round 1: project the web transcript from append-origin events

Replace the surface-ordered fold with a log-ordered human transcript: append-origin surface events at their own log positions plus one marker per landed compaction checkpoint. Command folding, the tool-call index, and the rev-keyed memo carry over unchanged. Removes foldDegraded, the padding sentinels, baseSeq, and degradedSeqs() -- they existed only to satisfy the core fold's seq === index assertion. That also closes the pagination hole A1 exposed: a page can carry a checkpoint whose shadowed range fell outside the window, and nothing resolves surfaceOp.start anymore.
