You have unrelated changes in your PR.
Replace direct cats-file reading with r.info -e (JSON format) to verify the preserved title. The cats file is an internal format; using the public API is more robust and is consistent with how other tests and tools read raster metadata.

@petrasovaa Cleaned up the branch, the unrelated commits were fixes for CI failures that came up while working on this PR and should have been separate PRs. Test now uses r.info -e with JSON format as suggested. |

- Remove extra braces around title-preservation block; move variable declarations to the top of the enclosing block - Use Rast_get_cats_title() instead of accessing the struct field directly - Use grass.tools Tools API in the test instead of grass.script - Drop unnecessary -e flag from r.info call in the test

Summary
Fixes #7199.
When
rules=is used inr.category, the raster title gets overwritten because the category structure is initialized with an empty title. As a result, any previously set title is lost.This change preserves the existing raster title while still replacing category labels based on the provided rules.
Testing
r.supportr.category rules=r.info
