this update is mostly about migration tooling, better player resolution, and support/debug quality of life.
also had some internal cleanup and an important fix for velocity running in client mode.

so whats new:

- added `/cb dump` for support snapshots (sanitized upload + local file export)
- added `/cb migrate` to migrate script files to the current schema
- migration is script-only now. there was a short config migration path but that got reverted again
- added `player-arg` per command for `target-required` and `schedule-online`
- added remote uuid resolving between connected proxies (`RESOLVE_UUID`) + local `UserCache` + Mojang fallback
- added `OFFLINE_PLAYER` argument type with suggestions support
- reworked schedule-online / player tracking flow to be more reliable and added clearer warning logs when player resolution fails
- fixed double command descriptions in command registration output
- fixed velocity client mode startup crash (`ClassNotFoundException: org.bukkit.command.CommandSender`)

breaking changes:
- scripts now require `version: 4`
- older scripts must be migrated first
- internal runtime files moved into the `data/` subdirectory

latest commit: e951a9e

this version brings some nice additions mostly around target-required
and player tracking across proxies. the wiki has been fully rewritten for this version so make sure to check that out.

so whats new:

- target-required per command option. this makes sure the player is actually on the target server before dispatching the command. also works when a proxy is in client mode so it checks across all connected proxies not just the local one
- per-command cooldowns, the old pipeline cooldown stage is gone
- player presence tracking. backends and client mode proxies now sync their player lists to the proxy. the full list only gets sent once on auth and after that only join/leave deltas get sent so you dont have to worry about huge packets even with like 30k players
- added PLAYERS argument type for velocity
- scripts now require version 3

breaking changes:
- removed Server.timeout from the config
- removed some unused config values
- script version 3 is now required, older versions wont work anymore
