Recording in Session kept a second copy of every event for every session, including local evals and embedders. Serializing lazily on the first replay also let a concurrent diff land before the cache write, so later replays served pre-diff output.

Introduces an experimental "replay" feature for the
evixCLI, allowing users to quickly replay the results of a previously completed daemon-backed evaluation without re-running Nix. The replay system is opt-in, does not check for changes in source files or environment variables, and is invalidated by certain actions likedifforwatch. I've updated benchmarking scripts and documentation to measure and compare the performance of the replay feature alongside other evaluation modes. To nobody's surprise, replay is shown to be significantly faster in repeated runs.*: not really incremental evaluation :)
