Two regressions from the previous CI install:
- Installing opencode-ai globally in server-ci/server-tests caused
opencode-agent.test.ts (gated on \`hasOpenCode\`) to start running
for the first time and surface real but unrelated test breakage.
Trim the install to claude-code, which is all that's needed for the
Claude e2e tests that motivated the change.
- claude-agent.integration.test.ts's supportedModels test calls the
SDK's \`query()\` directly (bypassing ClaudeAgentClient) and didn't
pass \`pathToClaudeCodeExecutable\`. The 0.2.71 SDK had a bundled
cli.js fallback; 0.2.133 doesn't, so on Ubuntu CI it tries the
per-platform binary path (\`...claude-agent-sdk-linux-x64-musl/claude\`)
which isn't installed via the \`claude-code\` global. Resolve the
binary explicitly in the test and pass it as the SDK option.
