* perf(terminal): mount only the visible pane on a worktree switch Activating a worktree mounted a TerminalPane for every tab it holds, not just the one on screen. Cold-activation deferral existed for this but engaged only past four deferrable hidden tabs, which exempted the 2-5 tab worktrees that make up almost every real switch. Deferral now engages for any deferrable hidden tab, and the siblings it skips are admitted one per idle frame after the reveal, capped at the population the old threshold would have mounted eagerly. Steady-state pane, WebGL-context and heap population are therefore unchanged; only the frame the mounts land on moved. * fix(terminal): judge admission eligibility on the largest deferred set seen Review found the launch worktree never warms up: it is restored active before hydration opens the startup gate, so admission read an empty deferred set, cached ineligible, and never recomputed once the real plan landed. Judge on the high-water mark instead - an over-cap worktree still stays ineligible as its set drains, but a later plan is seen. Also from review: the e2e WebGL counter read getPanes(), which returns a public projection with no webglAddon field, so it was always 0; read getRenderingDiagnostics() instead. Filler worktrees now clean up on failure (testRepoPath is worker-scoped), and the restore metric is named for what it measures rather than implying a pixel assertion. * test(e2e): wait for the reveal to restore, and scope the latency budget off CI CI failed with 'revealed terminal never restored its content': the harness sampled a fixed 4s window, which a shared runner can outlast, so a slow restore was recorded as no restore. Poll for the restore instead. Also stop asserting a latency budget on CI. Shared runners cannot hold a threshold; the structural invariants (one pane mounted by the switch, warm set restored) are exact and stay asserted everywhere.
