Bump cppzmq from 4.5.0 to 4.11.0 and MuJoCo from 3.2.6 to 3.2.7 after validating the dependency upgrades locally.
Bump the Conan OpenCV dependency to 4.13.0 and update the camera module to pass PNG compression options as an OpenCV key-value pair. OpenCV 4.13 rejects malformed one-element encoder parameter vectors, which caused OpNav image processing scenarios to fail during camera image encoding. Add release note and known-issues entries for the OpenCV 4.13 compatibility fix.
Bump the MuJoCo dependency to 3.7.0 and update the MuJoCo dynamics wrapper to read and write spec object names through the new element-name APIs. MuJoCo 3.7 moved names off individual spec structs, so direct `object->name` access no longer builds for bodies, sites, joints, equalities, and actuators. Add release-note and known-issues entries for the MuJoCo 3.7 compatibility fix.

LGTM. I like the helper methods for mujoco.

Description
This branch updates several Conan-managed dependencies and applies the compatibility fixes needed for the upgraded libraries.
Commits are organized as follows:
de6b178e4fupdatescppzmqfrom 4.5.0 to 4.11.0 and MuJoCo from 3.2.6 to 3.2.7.fba042d734updates OpenCV from 4.5.5 to 4.13.0 and fixes camera PNG encoding by passing OpenCV encoder options as key-value pairs.e5d606d76cupdates MuJoCo to 3.7.0 and updates the MuJoCo dynamics wrapper to use the MuJoCo 3.7 element-name APIs for spec object names.Verification
Validated the dependency upgrades with focused builds and tests:
scenario_OpNavAttOD.py.All unit tests completed as expected.
Documentation
Added release-note snippets for the OpenCV 4.13 camera encoding fix and the MuJoCo 3.7 spec object name API update. Updated
bskKnownIssues.rstto document both compatibility fixes.Future work
No follow-up work is currently planned.
