feat: install claude code cli in devcontainer image

[venkatamutyala]

Installs the Claude Code CLI into the devcontainer image. The image already sets CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1 but never actually installed the CLI — this adds it.

What changed

.devcontainer/Dockerfile:

• Pinned version arg with a Renovate annotation (matches every other tool in this file):

  # renovate: datasource=npm depName=@anthropic-ai/claude-code
  ARG VERSION_CLAUDE_CODE=2.1.197

• Install step in the USER vscode section (so it lands in the vscode user's ~/.local/bin, already on PATH):

  RUN curl -fsSL https://claude.ai/install.sh | bash -s ${VERSION_CLAUDE_CODE}

Why the native installer (not npm install -g)

node/npm are provided by a devcontainer feature, which is applied after the Dockerfile builds — so npm isn't available at image-build time and npm install -g @anthropic-ai/claude-code would fail. The native (nodeless) installer downloads a standalone binary and needs no runtime. Its version arg tracks the same releases as the npm package, so Renovate's datasource=npm depName=@anthropic-ai/claude-code keeps it current.

Arch-aware (multi-arch ready)

The installer auto-detects platform (x64/arm64, and musl vs glibc), so like the cloudflared change it keeps working if this image becomes a multi-arch build. Verified the pinned version's manifest and linux-x64 binary both resolve (HTTP 200).
