MP4 track timing was numerically unasserted. Every operator in the PTS-to-ticks, duration, tkhd_dur and ctts chain could be flipped and the whole suite stayed green, because no test decoded an output file and checked a concrete number — the existing tests assert box presence and gross container shape only. That is the crate's worst failure mode: a title muxes "successfully" with silently wrong A/V sync or total duration, and nothing above can tell. The new tests build tracks with known PTS deltas and compare the emitted stts, ctts and tkhd.duration against computed values. Also lifted the faststart slack rule out of the match guard into faststart_fits(). A leftover hole of 1-7 bytes cannot be expressed as any ISO-BMFF box, since a box header is 8 bytes, so finish() must fall back to moov-at-end rather than write a free box that lies about its own size. The condition now has a name and a test instead of being an unexplained `g == 0 || g >= 8` inside a pattern guard.
