Description

When running rtk gradle, the filtered output includes extra blank lines:

  1. Leading blank lines at the start of output
  2. Extra newline when stderr is empty (stdout + '\n' + empty stderr)

Expected: Clean output without leading/trailing blank lines. Actual: Extra blank lines appear in filtered output.

Research direction
Examine the source code for the `rtk gradle` subcommand, particularly the output filtering logic. Look for how it concatenates stdout and stderr. Identify where leading or trailing newlines could be removed. Consider using `trim()` or similar in Rust to clean up. The existing comment thread may provide hints; if not, a simple fix might involve trimming the output before display.
