Add wrap_around parameter to RoundRobin node to control wrap-around behavior

[SteveMacenski]

This PR implements the feature requested in #5033 to add a boolean parameter that controls whether the RoundRobin behavior tree node wraps around to its first child after the last one fails.

Changes

• Added wrap_around boolean parameter (default: false) to RoundRobin node
• When wrap_around=false, node returns FAILURE instead of wrapping to first child
• Updated XML node definition to include new parameter
• Existing behavior tree XMLs will use new non-wrap-around behavior by default

Problem Solved

Addresses issue where RoundRobin index can become misaligned with RecoveryNode retry counter when used in recovery sequences. The new default behavior (no wrap-around) ensures each recovery action is performed once and only once.

Fixes #5033
