Add circular_dynamic_buffer wrapping, boundary, and fuzz tests

[sgerbino]

Cover code paths the existing testMembers/testGrind harness cannot reach: two-segment buffer splits when data wraps around the ring, clamping behavior for oversized commit/consume, the in_pos_ reset optimization in consume(), capacity-1 boundary, and a 2000-iteration fuzz test against a reference model.

Important

Review skipped

Review was skipped due to path filters

⛔ Files ignored due to path filters (1)

• test/unit/buffers/circular_dynamic_buffer.cpp is excluded by !**/test/**

CodeRabbit blocks several paths by default. You can override this behavior by explicitly including those paths in the path filters. For example, including **/dist/** will override the default block on the dist directory, by removing the pattern from both the lists.
