* fix(server): keep cold diffs out from behind background git fan-out Add a background lane to the git process scheduler and run reconciliation checkout reads, observation-driven workspace refreshes and background fetches in it. Bound reconciliation checkout reads to four at a time. Stop the Linux file observer's startup scan from reporting existing files as creates, which made every cold diff compute and discard its first revision. * fix(server): pick the git job when its start token fires Background jobs that already reserved a start-rate token no longer start ahead of normal work submitted after them. * fix(server): re-read the working tree once its watcher covers it The Linux observer no longer reports pre-existing files at startup, so an edit made between a workspace's first snapshot and its watcher subscribing reached no consumer. WorkspaceGit now runs one background working-tree read once observation setup completes with a live watcher. Demand refreshes keep the caller's Git lane instead of forcing normal, so user actions running at high priority are not demoted. Scope the populated-tree observer test to Linux (FSEvents replays recent writes) and update the observer benchmark test, which expected the removed startup batch. * fix(server): re-read checkout metadata once observation covers it A branch switch made before the Git metadata watcher subscribed left the cached branch stale. The post-coverage read now refreshes structure as well as the working tree, matching the refresh the Linux startup events used to trigger.
