/**
 * Claude Code Provider
 *
 * Wraps `@anthropic-ai/claude-agent-sdk` so consumers can use a local
 * Claude Code installation — including Claude Pro/Max subscription
 * accounts authenticated via `claude login` — through the same
 * BaseAIProvider interface as the other providers.
 *
 * Tradeoffs vs the direct Anthropic API provider:
 * - Authenticates via the local CLI, so subscription users (no API key)
 *   can use it.
 * - Requires `claude` to be installed and logged in on the host.
 * - Higher latency (shells out to a CLI process per request).
 * - Designed for agent workflows, but used here in single-turn mode
 *   (maxTurns: 1, no tools) for plain text completion.
 *
 * @see https://docs.anthropic.com/claude/docs/claude-code-sdk
