HyAnnouncer - Announcements - Broadcasts - Sounds

Requires **Hytale 0.5.6+** (Java 25). Build with JDK 25 toolchain via Gradle.

### Added

- **Granular permissions:** Replaced OP-only command access with `hyannouncer.command.*` permission nodes. OP (`*`) still grants full access.

  - `hyannouncer.command.use` — `/ha info`, `/ha list`

  - `hyannouncer.command.reload` — `/ha reload`

  - `hyannouncer.command.broadcast` — `/ha broadcast`, `/ha test`

  - `hyannouncer.command.send` — `/ha send`, `/ha sendplayer`

  - `hyannouncer.command.gui` — `/ha gui`

  - `hyannouncer.command.control` — `/ha start`, `/ha stop`, `/ha startsys`, `/ha stopsys`

  - `hyannouncer.admin` or `hyannouncer.*` — full HyAnnouncer access

### Changed

- **Hytale 0.5.6 / Java 25:** Bumped `ServerVersion`, Java toolchain, and build docs for hytale-downloader layout.

- **API:** Replaced removed `Player.getDisplayName()` with `PlayerRef.getUsername()` via `PlayerHelper.getUsername()`.

- **GUI command:** `/ha gui` migrated from `AbstractAsyncCommand` to `AbstractPlayerCommand` because `Player` no longer implements `CommandSender` in Update 5.

- **Version display:** Startup log and `/ha info` now read version from plugin manifest instead of hardcoded string.

- **Build:** `build.gradle` supports `local.properties` and `HYTALE_HOME` / `HYTALE_SERVER_JAR` env vars for locating `HytaleServer.jar`.

- **Documentation:** Updated commands, permissions, troubleshooting, and CurseForge descriptions for 1.1.7.

### Fixed

- **Announcement permissions:** Config `Permission` fields on chat/title/notify/welcome announcements now use the real Hytale permission system via `PlayerHelper`.

- **Leave-world messages:** Default white "player left world" chat is now suppressed when join-leave is enabled, using `RemovedPlayerFromWorldEvent.setBroadcastLeaveMessage(false)` (mirrors join suppression on `AddPlayerToWorldEvent`).
