Feat: Overlap movie output and cut per-frame fast-mode work

Browse Source 
- Gather the union of every movie frame's all-sky tiles once and read them in bounded batches, replacing the per-frame prefetch scan and log.
- Fuse the fast supersampled-buffer clear into the FFTW pack pass so a resolved frame starts clean with no serial memset.
- Split parallel HDR->RGB8 tone mapping from PNG encoding.
- Add a bounded single-producer/single-writer movie output queue used by both observer movies and multi-frame imported lens maps, with writer timing and error propagation.
- Add --png-compression-level and --movie-output-workers shared|reserve-one.
- Add --fast-fftw-plan estimate|measure|wisdom|wisdom-update with strict wisdom identity sidecars.
- Add staged movie timing, regression tests, and docs.
