* fix hls close revision file at reader deadline
Move the progressive revision reader onto its own task and feed the
response stream through a bounded channel. At the deadline the watchdog
aborts the reader, so the file handle and revision pin are released
even if a stalled client never polls the stream again.
Each open revision file now holds its own pin, so GC cannot retire a
revision while a handle is open, including one held by an in-flight
blocking read.
