release(3.2.1): lockstep version alignment with the engines at 4.3.1

[rennf93]

No agent behavior changes. Shipped so the agents family moves in lockstep with the engines at 4.3.1 while guard-agent-ts carries the js/polynomial-redos fix (CodeQL HIGH, agent-ts PR #23). Version bump + changelog entry only.

Summary by CodeRabbit

• Bug Fixes
  • Updated guard-agent-ts to eliminate a potential slowdown when removing trailing slashes from configuration and transport values.
• Release
  • Released version 3.2.1, aligned with engines 4.3.1. Agent behavior is unchanged.
