Port OpenClaw skills: add clawdbot metadata support + deps

- skills.py: recognize "clawdbot" metadata key alongside "nanobot"
  so OpenClaw SKILL.md files work without rewriting
- Dockerfile.oauth: add skill binary dependencies
  - APT: ffmpeg, jq, tmux, gh
  - Go: blogwatcher, blucli, gifgrep, sonoscli, wacli
  - Brew: gogcli, goplaces, songsee, gemini-cli, obsidian-cli,
    himalaya, openai-whisper
  - npm: @steipete/oracle
  - uv: nano-pdf
