[I] [Bug] Terminal run error truncation can create invalid UTF-8 text [rocketmq-dashboard]

["Wang1rrr (via GitHub)" <gi...@apache.org>]

Wang1rrr opened a new issue, #7001:
URL: https://github.com/apache/rocketmq-dashboard/issues/7001

   ### Description
   
   `AiRunExecutor` limits persisted terminal errors with `String.substring`, counting UTF-16 code units. A valid provider error containing a supplementary character at the 1,000-character message boundary is cut between its surrogate pair. The run repository then receives a string that cannot be encoded as valid UTF-8. The same helper handles the 64-character error code.
   
   Errors consisting of supplementary characters are also truncated even when they fit in the database's character budget (for example, 750 emoji become 500).
   
   ### Reproduction
   
   Have the stub provider fail with an error message of 999 ASCII characters, one emoji, and a suffix. Run it through `AiRunExecutor` and inspect the persisted run update: `StandardCharsets.UTF_8.newEncoder().canEncode(errorMessage)` is false.
   
   ### Expected behavior
   
   Keep supplementary characters whole and use the existing code-point-aware `TextBounds` helper, while retaining the current error field limits and blank/trim behavior.
   
   ### Validation
   
   Three regression cases fail against the current base: emoji and CJK extension boundary cases, and a 750-code-point message that should fit. They pass with the candidate fix. This reproduction checks the repository arguments and UTF-8 encodability; it does not use a live MySQL server.

   Resolved by #6998 (merged into `rocketmq-studio` as `1053cd4be`). The fix was originally submitted in #7002 and consolidated into that commit.
