- Add coder/workspace.Dockerfile with Node.js 22, wrangler, claude-code,
and Playwright deps pre-installed. Eliminates ~3 min of installs on
every workspace startup.
- Add CI workflow to build and push to registry.samson.media/coder-workspace
- Fix slash command: -p mode doesn't support /commands, so read the .md
file directly, strip frontmatter, substitute $ARGUMENTS, pass as prompt
- Switch workspace image from codercom/enterprise-base to custom image
