  - Fix --remote option to replication start
    
    Declaring --remote as a 'Set<String>' field trips args4j's
    Setters.create(), which only treats List, Map, and Arrays as
    multi-value containers. Use a method-based @Option that adds
    each --remote value into a Set<String> to work around this.

  - Merge branch 'stable-3.10' into stable-3.11
    
    * stable-3.10:
      Improve the wording to explain url matching

  - Add RoundRobin URL selection per remote
    
    Introduce a `urlDistributionStrategy` config flag on remote sections.
    When set to `roundRobin`, each replication push selects one URL from the
    configured list in round-robin order rather than pushing to all URLs
    simultaneously.
    
    This is particularly useful in high-availability setups where multiple
    replica hosts share a single NFS backend. Pushing to all URLs at once
    would result in redundant writes to the same underlying storage.
    Round-robin distributes push load evenly across hosts while ensuring
    each push is executed exactly once.

  - Improve the wording to explain url matching
    
    Everytime I use this switch I struggle and end up having to look a the
    code to figure out how it works. Help clarify how the match works.
