Pull request overview

This PR adds support for the Bun runtime to OpenWorkflow by implementing runtime detection for SQLite backends. It fixes the issue from the reverted PR #249 where the code depended on global require, which isn't available in Node ESM environments.

Changes:

• Implements runtime detection to use bun:sqlite for Bun and node:sqlite for Node.js
• Creates a common Database interface that both SQLite implementations satisfy
• Uses createRequire from node:module to avoid dependency on global require
• Adds comprehensive Bun support to all documentation
• Adds a separate Bun test CI workflow
