Add rmw_zenoh_cpp as RMW vendor and update dist

[minggangw]

Changes:

• lib/rmw.js

  • Added ZENOH: 'rmw_zenoh_cpp' to RMWNames constants
  • Added missing iron, jazzy, and kilted distro entries to DefaultRosRMWNameMap (all default to rmw_fastrtps_cpp)
  • Added safe fallback to getRMWName() — returns rmw_fastrtps_cpp when the distro is not in the map and RMW_IMPLEMENTATION is unset, preventing undefined from causing incorrect feature gating

• test/test-subscription-content-filter.js

  • Updated isContentFilteringSupported() to exclude rmw_zenoh_cpp, which does not support content filtering

Context:

rmw_zenoh_cpp was promoted to Tier 1 in ROS 2 Kilted Kaiju and is actively referenced in rclpy tests for conditional behavior. rclnodejs was missing it entirely from its RMW vendor registry. The DefaultRosRMWNameMap was also missing entries for multiple known distros (iron, jazzy, kilted), and getRMWName() had no fallback for unmapped distros.

Fix: #1486

Pull request overview

Adds awareness of the rmw_zenoh_cpp RMW implementation to rclnodejs and updates distro→default RMW mapping, with a corresponding test adjustment to avoid running content-filtering tests on an unsupported RMW.

Changes:

• Add ZENOH: 'rmw_zenoh_cpp' to RMWNames.
• Add missing jazzy and kilted entries to the default ROS distro → RMW mapping.
• Update content-filtering test gating to also exclude rmw_zenoh_cpp.

DistroUtils recognizes the iron distro, but DefaultRosRMWNameMap still has no entry for it. With RMW_IMPLEMENTATION unset, getRMWName() will return undefined on Iron (and on any other known-but-unmapped distro), which can lead to incorrect feature gating (e.g., tests treating content filtering as supported). Add an iron mapping (likely RMWNames.FASTRTPS) and/or provide a safe fallback when the map lookup is missing.
