On-node empirical testing of this bmx v1.6 build showed that raw2bmx's
rdd9 writer with --part already maintains a live, correct header Duration
as the file grows: ffprobe reads a growing duration mid-write (e.g. 2.04s
of a 10s clip while still recording), and the structural-metadata
Duration fields (tags 02020008 / 30020008) hold the real frame count
(0x33 = 51), not -1.
The dur-patch.py added in the previous commit searched the header for
Duration=-1 (0xFF*8) and found 0 fields on rdd9 ("[dur-patch] 0 Duration
fields"), so it was a no-op. Worse, opening the MXF r+b to patch it while
raw2bmx appends over CIFS is a concurrency hazard. Remove it entirely and
rely on raw2bmx's native growing Duration. rdd9 + --index-follows remains
the Premiere-recommended growing flavour (Sony XDCAM essence, index in the
essence partition).
Verified on-node (ffprobe/byte-probe). Live edit-while-record in Premiere
itself still requires user confirmation.
