Hy4ri 304a90186a Fix: Avoid eager List allocation in countDiffLineStats for large diffs ...

Replaced `diff.split("\n")` with `diff.lineSequence()` in `FileRenderers.kt`'s `countDiffLineStats()` method. This prevents massive `ArrayList` allocations on the heap when processing multi-thousand-line diffs during tool card rendering, improving memory efficiency by evaluating the lines lazily.

Added comprehensive unit tests in `FileEditSupportTest.kt` covering empty diffs, header filtering, CRLF handling, and large multi-line diffs.
