Modulate encoder MPL source package

MPL-2.0 source files for Mediabunny 1.54.0 and Modulate's AAC wrapper 1.54.0-modulate.1. Matching FFmpeg source, generated module and rebuild materials are published separately alongside this archive.

Mediabunny source is copied byte-for-byte from the installed npm package. The AAC wrapper/worker/bridge and shared helpers preserve upstream v1.54.0 source. The local package README describes the modified metadata, bundle script and independently rebuilt FFmpeg artifact. Copyright and license notices are preserved; source is offered under MPL-2.0 without additional restrictions. SOURCE_MANIFEST.json identifies exact files and hashes.

The adjacent /licenses/ page provides the complete pinned FFmpeg source (LGPL-2.1-or-later), minimal patch, C bridge, build/relink recipe and complete local package. See modulate-aac-corresponding-source-1.54.0-modulate.1.tar.gz and ffmpeg-aa483bc42201e673cf7172be5205c14ada26bdbd.tar.gz. These pins identify the NEW independently built replacement; they do not identify the old upstream npm binary.
