/**
 * Phase 4c — MCP project-dir resolution.
 *
 * Resolved ONCE at MCP server startup; the MCP does NOT track the
 * AI CLI's current working directory mid-session. Switching repos
 * requires opening a new AI CLI session. The plan calls this out
 * explicitly and the README + `cursell hub init` success message
 * remind the user.
 *
 * Resolution order:
 *   1. `CURSELL_PROJECT_DIR` (operator override)
 *   2. `CLAUDE_PROJECT_DIR` (Claude Code injects this when MCP
 *      subprocesses are spawned)
 *   3. `process.cwd()` (default)
 *
 * The chosen path is logged to stderr at startup so a misconfigured
 * env doesn't lead to silent "agent not pinned" failures.
