v3.4.1

Automated release: version and notes generated from pull requests merged since 3.4.0.

Fixed

• The plugin tree carries its listing icon and no longer carries the npx installer. The
  Claude plugin directory's validation of the 3.4.0 plugin branch reported no icon (it reads
  .claude-plugin/icon.png, once, at the first submission) and flagged bin/install.js three
  times: a download-and-run pattern, a bin/ folder, and a file type outside the allowed set.
  The installer is what npx ffmpeg-skill runs; a plugin host does the installing and nothing in
  the skill calls it. The branch now ships assets/icon.png as .claude-plugin/icon.png, leaves
  bin/ out, and its package.json no longer names a bin. The npm package is unchanged.
  The same validation held six findings as "uses a credential from the user's machine". None
  reads a credential: each is a file that names a URL and also holds a word the check reads as a
  credential source (pass --overwrite, a $FFMPEG_SKILL_HW reference, an environment lookup).
  Two came from the repository README, so the plugin tree now carries a short README of its own,
  and references/workflow.md says "add --overwrite". The three that remain
  (docs/contract.md, scripts/_contract.py, scripts/_common/runner.py: an ffmpeg.org link
  beside a configuration variable) are left for the directory's reviewer.

Changed

• A plugin install copies 2.7 MB, not the repository. The marketplace entry now names the
  ffmpeg-skill/ directory of the plugin branch (a git-subdir source) instead of the
  repository root. Installed from the real branch at 3.4.0 by Claude Code 2.1.322 and Codex 0.167:
  2.7 MB each, no .git. The README's marketplace add commands gain --sparse .claude-plugin,
  which takes the marketplace checkout from 50 MB to 1.1 MB (Claude Code) and from 66 MB to 2.2 MB
  (Codex). Gemini CLI still clones the repository.
  The plugin route now needs Claude Code 2.1.69 or later (2.1.288 with git older than 2.39);
  npx ffmpeg-skill is unchanged.
