v1.0.30pre9

Fixes the reconnect loop from pre8: a recovered stream no longer re-triggers its own recovery until the session dies.

• The post-resume media-burst detector no longer misreads the whole session's history as a fresh loss burst.
• Server input-channel silence after a pad revive is no longer treated as a dead session (quiet games never send any). ZL+ZR+up twice remains the manual reconnect.
• Retry on the failure screen no longer cancels itself when pressed immediately.
