Model Context Protocol server for Bottlenecks database - enables AI agents like Claude to interact with bottleneck data

/**
 * Version awareness for the bottlenecks-mcp-server npm package.
 *
 * Previously server.ts hardcoded version: '1.0.0' in two places, which had
 * drifted out of sync with the actually-published package (1.3.6 at time of
 * writing) — a connected AI agent had no way to tell it was talking to a
 * stale server, let alone that a newer one exists. PACKAGE_VERSION fixes the
 * "what am I" half; checkForUpdate() fixes the "is there something newer"
 * half by checking the real npm registry.
