Two issues that surfaced when story 1 ran in the adopted huskies-server sled: 1. Dockerfile.base: the base image had no nodejs / claude CLI, so every coder agent spawn in an adopted project sled failed with `Unable to spawn claude: No viable candidates found in PATH`. Install nodejs + @anthropic-ai/claude-code in the base image so every sled built from it can spawn agents out of the box. 2. worktree/create.rs::install_pre_commit_hook: `git config --worktree` requires `extensions.worktreeConfig = true` to be set on the repo config; without it, every worktree creation logged a noisy `Pre-commit hook install failed` warning. Enable the extension idempotently before the per-worktree hooks-path set so the hook install succeeds cleanly. After this, rebuild huskies-project-base and recreate any adopted project containers to pick up the CLI. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
