v5.2.19

The Context7 MCP moved from a local npx command to the remote HTTP endpoint https://mcp.context7.com/mcp in the Linux, macOS, and Windows OpenCode configs, which requires the CONTEXT7_API_KEY environment variable and enables remote execution without a local Node.js dependency. deploy.ps1 switched its OpenCode config deployment from overwrite to merge, preserving existing user settings while adding or updating MCP servers from the dotfiles, with a deep comparison that detects actual changes before updating and the new output messages (created), (merged N server(s)), and (up to date). Claude config deployment changed from selective file copy to full directory recursion, so the entire .claude/ directory including hooks, tdd-guard, and all scripts deploys and new files are included automatically, which simplifies maintenance. The README deployment example output now shows "Claude configs" and "OpenCode config" lines, and a Deploy Script Behavior section documents the merge and overwrite behavior and the OpenCode merge output messages.
