"""
Post text + optional image/video to Bluesky/federated PDS.
Key reliability choices:
- Video uploads go through https://video.bsky.app first (best client playback compatibility).
- getServiceAuth uses:
aud = did:web:<your-pds-host>
lxm = com.atproto.repo.uploadBlob
- Handles 409 already_exists from video service by reusing jobId.
- Uses raw lexicon dict embeds (NO AppBskyEmbedVideo typed model), avoiding BlobRef SDK mismatch.
- Optional direct-PDS fallback for video.
- ffmpeg compression enabled by default (disable with --no-compress-video).
