SolitaryThinker c6468e8def [misc]: collect fastvideo/tests/batching in the Modal unit-test lane (#1453) 
The new batching unit tests (admission, signature) were not collected by
any CI lane. stages/ is already collected on main, so only batching/ is
added.

SolitaryThinker 2c0d9a0828 [bugfix]: keep completed results when a prompt-file batch group fails (#1453) 
The dynamic-batching prompt-file branch let a single failed group raise
out of generate_video, discarding every completed result (and tripping
the strict zip). Restore the legacy per-prompt tolerance: a failed group
now yields an error entry per prompt, keeping results aligned with the
input prompts while completed videos survive.

SolitaryThinker b9876ee06d [bugfix]: fail fast when submitting to a stopped batch scheduler (#1453) 
submit() after stop() enqueued jobs the drained run loop would never
resolve, hanging the caller forever on the future. Raise immediately
instead.

SolitaryThinker a568406b8c [bugfix]: drain queued jobs greedily when batching delay is 0 (#1453) 
With the default batching_delay_ms=0, _collect_batch called
wait_for(timeout=0) which timed out before draining the queue, so every
dispatched batch had size 1 and dynamic batching silently no-oped. When
delay is 0, drain already-queued jobs non-blocking (until empty,
max_size, or an incompatible job) instead of waiting.

SolitaryThinker 39cc075452 [bugfix]: reserve batch output paths so duplicate prompts do not collide (#1453) 
Batch mode resolves every output path via _prepare_output_path before any
file is written, so the os.path.exists dedupe never fired and duplicate
prompts (or prompts equal in their first 100 sanitized chars) overwrote
each other. Track paths reserved within the batch and suffix duplicates,
matching what the legacy sequential path produces for the same inputs.
