Cédric Verstraeten 17c1c5b04b Drop truncated GOPs at loop/restart seams ...

Buffer and conditionally drop a pending GOP when an upstream loop/restart emits a premature IDR. mp4.go: add gopBuffer and bufferedSample types, hold samples until the next video keyframe, detect a seam by comparing the new keyframe interval against the previous cadence (SeamGapDivisor) and drop the short/truncated tail GOP or commit buffered samples. Add commitBufferedGOP and commitSampleToTrack helpers and flush the final buffered GOP on Close. mp4_loopseam_test.go: update test descriptions, expectations and names to assert the truncated tail GOP is dropped exactly once across different GOP sizes. Dockerfile and Dockerfile.arm64: re-declare ARG VERSION inside the build stage and only derive git describe when VERSION is unset or the default 0.0.0 so build-arg values are respected. Add a binary MP4 fixture used by the tests.
