Rename galaxy_creation to galaxy; add character creation skeleton

- Rename GalaxyCreationPlugin -> GalaxyPlugin, AppState::GalaxyCreation
  -> AppState::Galaxy, module path galaxy_creation -> galaxy (folder
  rename preserves git history via git mv).
- Rename GalaxyCreationSpawned -> GalaxySpawned, despawn_galaxy_creation
  -> despawn_galaxy.
- Update AGENTS.md module layout, plugin pattern example, and naming
  table for the new names.
- Add apps/game/src/gameplay/character_creation/ skeleton: placeholder
  UI with Confirm (-> InGame) and Back (-> Galaxy) buttons plus Escape
  shortcut. Wired into main.rs via CharacterCreationPlugin.

 ### When to add a file vs a folder
 
-- **Default**: one file per feature (e.g. `main_menu.rs`, `galaxy_creation.rs`).
+- **Default**: one file per feature (e.g. `main_menu.rs`).
 - **Promote to a folder** when the file exceeds ~300 lines, mixes UI + logic + data, or needs shared private helpers.
 - A promoted folder should expose its public API via `mod.rs` and ideally bundle its systems into a Bevy `Plugin` (see pattern below).
 
 ### Plugin pattern (recommended once a folder exists)
 
 ```rust
-// src/gameplay/galaxy_creation/mod.rs
+// src/gameplay/galaxy/mod.rs
-pub struct GalaxyCreationPlugin;
+pub struct GalaxyPlugin;
 
-impl Plugin for GalaxyCreationPlugin {
+impl Plugin for GalaxyPlugin {
