v0.3.0

Features

• Export QR sequences as animated GIF (#27)
• Cap encoded block degree (#30, closes #23): the fountain encoder now uses a Robust Soliton distribution (c = 0.2, δ = 0.5) truncated at maxDegree (default 32). For large inputs this needs roughly 15% fewer frames and decodes much faster (k=1000: 144% → 128% mean overhead, ~40× faster decoding; k=3000 previously ran out of memory).
  • luby-transform: createEncoder(data, sliceSize, options) accepts { compress?, maxDegree?, random? }. A boolean third argument still means compress. New export DEFAULT_MAX_DEGREE.
  • @qifi/generate: new maxDegree option.
  • qifi CLI: new --max-degree <count> flag.

Fixes

• Prefer the rear camera by default (#29, closes #26): the scanner requests facingMode: environment unless the user explicitly picked a camera, no longer triggers extra permission prompts, and serializes camera switching to avoid leaked streams.

Compatibility

• No breaking API changes. The frame format is unchanged, so scanners and decoders from earlier versions can decode frames produced by 0.3.0.
• Behavior change: default degree distribution changed from uncapped Ideal Soliton to capped Robust Soliton; frame headers are now bounded (≤ 144 bytes).

Docs

• Document maxDegree and the new degree distribution in the package READMEs.
