The replace_all field is incorrectly marked as required in the OpenAI schema. This conflicts with the actual struct definition in catalog.rs where replace_all has #[serde(default)] and #[schemars(default)], making it optional with a default value of false.

This will cause issues:

1. The LLM will always need to provide replace_all even when using the default behavior
2. This creates inconsistency with the JSON schema snapshot which correctly omits replace_all from the required array
3. OpenAI's strict mode will reject requests that don't include this field

Fix: Remove "replace_all" from the required array:

"required": [
  "new_string",
  "old_string"
],

Suggested change

	"required": [
	"new_string",
	"old_string",
	"replace_all"
	],
	"required": [
	"new_string",
	"old_string"
	],
