Stabilize Devcontainer Build by Recovering Interrupted dpkg State

[Copilot]

The Build Image GitHub Actions job was failing during Docker build because package installation entered an interrupted dpkg state (exit code 100). This update hardens the devcontainer build path by recovering package configuration before continuing.

• Root cause addressed: interrupted package manager state

  • In .devcontainer/Dockerfile, added an explicit recovery step after the Tailscale installer path to ensure any partially configured packages are finalized before later apt/dpkg work.

• Minimal Dockerfile change

  • No workflow or tagging logic changed.
  • Single-line functional fix in the existing install chain.

&& (curl -fsSL https://tailscale.com/install.sh | bash || echo "WARN: tailscale install failed, continuing") \
&& dpkg --configure -a \
&& rm -rf /var/lib/apt/lists/* \

Pull request overview

This PR hardens the devcontainer image build by adding a dpkg recovery step to handle interrupted package configuration states that can cause apt/dpkg failures (exit code 100) during Docker builds.

Changes:

• Add dpkg --configure -a immediately after the Tailscale installer step in the .devcontainer/Dockerfile install chain.
