Code Review

This pull request updates the documentation in README.md and src/Search_Replace_Command.php to clarify that the search-replace command handles JSON-escaped versions of search strings in non-regex mode. It also includes a new usage example for this functionality. I have no feedback to provide.

Pull request overview

Updates the wp search-replace documentation to explicitly cover a common real-world case: URLs stored in JSON where / is escaped as \/, so non-regex search/replace will still find and replace those values.

Changes:

• Document that non-regex mode also replaces the JSON-escaped form of the search string (e.g. http:\/\/...).
• Add a short example showing URL replacement that applies to both plain text and JSON-escaped data.

Nothing about this example really says JSON, it doesn't provide any additional value over the very first example above.

Let's remove.
