Added

• /f map now supports a size option: --size=<size>.
• Shared command argument parsing coverage for valued long options (--key=value and --key value), including error handling tests.
• New reusable faction member notification helper (FactionMemberNotifier) for consistent online-member notifications across features.
• New predefined factions system with separate pre-defined.yml storage and explicit in-memory reload flow.
• New /f predefined command tree (with /f prefined alias): create, claim, sethome, reload, and list.
• New predefined defaults and policy toggles in pre-defined.yml: enabled (default false), case-sensitive, and block-disband.
• /f info can now display relationship sections, configurable via:
  • factions.info.relations.show-allies (default true)
  • factions.info.relations.show-truces (default false)
  • factions.info.relations.show-neutrals (default false)
  • factions.info.relations.show-enemies (default false)

Changed

• /f map once default render radius increased to 3 via config default (factions.map.once-radius).
• /f map row suffix formatting no longer appends z=<value> at line ends.
• /f map tile hover text now uses explicit coordinate labels for clarity: Chunk X, Chunk Z, and Player Y.

• Improved relation workflow and UX:
  • /f relation now supports relationship alias.
  • Ally/truce now support pending-to-mutual confirmation flow.
  • Enemy/neutral relations are mirrored for consistency.
  • Ally/truce limits are enforced via relation limits.
• Tab completion improvements:
  • Fixed /f relation <faction> <relation> completion.
  • Fixed /f relationship ... completion.
  • Improved /f map completion for mixed argument order (on|off|once with --size).
• Join and relation notifications now use configurable message keys in messages.yml.
• Added predefined command permissions and configurable predefined messages in messages.yml.

Fixed

• Fixed invite acceptance join path that could fail with database NOT NULL constraint errors when player rows were first created.
• Faction members are now notified when a player successfully joins their faction.
• Predefined factions can be protected from disbanding (player and admin disband paths) when policy is enabled.
