The cron delivery path sent raw 'MEDIA:/path/to/file' text instead
of uploading the file as a native attachment. The standalone path
(via _send_to_platform) already extracted MEDIA tags and forwarded
them as media_files, but the live adapter path passed the unprocessed
delivery_content directly to adapter.send().
Two bugs fixed:
1. Live adapter path now sends cleaned text (MEDIA tags stripped)
instead of raw content — prevents 'MEDIA:/path' from appearing
as literal text in Discord/Telegram/etc.
2. Live adapter path now sends each extracted media file via the
adapter's native method (send_voice for audio, send_image_file
for images, send_video for video, send_document as fallback) —
files are uploaded as proper platform attachments.
The file-type routing mirrors BasePlatformAdapter._process_message_background
to ensure consistent behavior between normal gateway responses and
cron-delivered responses.
Adds 2 tests:
- test_live_adapter_sends_media_as_attachments: verifies Discord
adapter receives send_voice call for .mp3 file
- test_live_adapter_sends_cleaned_text_not_raw: verifies MEDIA tag
stripped from text sent via live adapter
