Two export killers fixed and the feature surfaced properly:
- TicketArena::allocate() reaps finished fire-and-forget slots on every
new submit, but RenderTask classified finished tickets by asking the
arena for their kind/time afterwards - any ticket that completed
before the next submit (all of them on the inline backend) failed
with 'Render ticket reported an unexpected timestamp' and the export
died after writing a header-only file. RenderTask now records each
ticket's delivery key at submit time instead.
- File > Export becomes 导出序列 (all 8 locales): the dialog offers a
sequence picker (any sequence in the project, the current one
preselected) instead of silently exporting the current one, and the
project bin's sequence context menu gains 导出序列 opening the same
dialog. Engines expose sequence_entries / current_sequence_id /
start_export_of.
- The export-project dialog drops its dead hand-typed path field (OK
already asked the platform save dialog).
- New end-to-end test: a one-second sequence exports to a real
H.264/AAC MP4 that probes and decodes back to the clip's content.
