+Rely on DiffProcessor for git diff pre-processing; remove raw char truncation, raise diff token safety, and improve logging
+
+- Removed raw character-based truncation of additionalContext — diffs are expected to be pre-processed by DiffProcessor instead of blind substring truncation.
+- Now validates pre-processed diff token count only and treats DiffProcessor as the primary sampler (DiffProcessor typically uses a ~100k token budget).
+- Increased MAX_DIFF_TOKENS safety net to 200,000 to cover edge cases and avoid false positives; updated logs to reflect pre-processed diffs.
+- Improved error messaging to indicate a likely DiffProcessor misconfiguration when pre-processed diffs exceed the safety limit.
+- Updated informational logs to state that a pre-processed git diff was added to context.
+
 ## 2025-11-04 - 1.9.0 - feat(context)
 Add intelligent DiffProcessor to summarize and prioritize git diffs and integrate it into the commit context pipeline
