_micRestartCount bounds the continuity auto-restart loop (_micMaxRestarts=20)
so a stolen audio session can't spin tight. But it only reset on
fresh-start / terminal-end / error -- never on a real onresult. So a long
mobile dictation with 20 natural pauses (each producing speech) hit the cap
mid-session and the mic silently stopped, undercutting the feature's whole
purpose ("keep dictation active through pauses").
Reset _micRestartCount=0 in sr.onresult: a real result proves the restarts
are PRODUCTIVE, not a failure spin. The cap still guards the failure case --
consecutive restarts that yield no speech (onend with no intervening
onresult) keep incrementing and trip the bound.
Regression test seeds the count AT the cap, fires a productive onresult, and
asserts the ensuing pause still restarts (count reset to 0 -> 1). Verified
fail-without / pass-with against boot.js.
