* Perf: the web keeps slow frames too; its clock is performance.now() (#9328)
now_ms() reads web_time::Instant, which is performance.now() on wasm, so
the web build records slow frames, reports perf.slowFrames and logs them
to the browser console. The stroke trace is off on the web for another
reason: it has no environment, stderr or files to write to.

* Perf: one frame stage record across egui's passes (#9328)
egui runs a frame's UI again when a pass asks for a discard (a sizing
pass). The second pass opened a new stage record after the first pass
closed its own, so a frame of two 30 ms passes was never slow and the
stroke trace gained a 0-move row per extra pass.
finish_frame now adds each pass's UI time to the record and leaves it
open while ctx.will_discard() says egui will run the pass again; the
last pass closes it. ui_start keeps the first pass's input time.

* Perf: a frame's stroke flag covers every pass
