fix: prevent duplicated character descriptions in prompts

CHANGELOG.yaml

@@ -48,6 +48,7 @@
   - "macOS Modifiers: Ctrl+click affordances throughout the UI now also accept Cmd (Meta) on macOS, where the OS reserves Ctrl+click for the system context menu. Tooltips, hints, and docs label the modifier as Cmd on Mac and Ctrl elsewhere. Affects regenerate, scene tools (narrator/director/actor/creative), world state manager, contextual generate, message asset image, autocomplete (Ctrl+Enter), and history navigation. (#261)"
   - "Game Loop Actor Iter: Fixed a bug where the `game_loop_actor_iter` event was only firing for player turns, so agents that listen for actor iteration (like passive narration) silently skipped AI turns."
   - "OpenRouter: Fixed redundant provider/model list fetches when multiple OpenRouter clients are configured. Concurrent `status()` calls all saw the fetched-flag as still false and each kicked off its own HTTP request; the fetches are now serialized with an asyncio lock and double-checked locking so only one request runs."
+  - "Character Prompts: Fixed duplicated character description in prompts. When the LLM-generated character sheet contained a `description` attribute (common — the extractor often emits one), it was rendered alongside the standalone description field, repeating the same text twice. Templates that render both now filter `description` out of the sheet (case-insensitive). Affects the dialogue, narrator, director (voice assignment), and creator (dialogue examples, dialogue instructions, character goals, contextual generate) prompt paths."
   improvements:
   - "System Prompt Override Indicators: The system prompt override list now shows a pencil icon next to entries that have an active override, making it easy to see which prompts have been customized."
   - "Search Strictness: The distance_mod embedding preset value is now a float (was int) with a range of 0.1–2.0, allowing both tighter and looser similarity matching. A 'Search Strictness' slider is now available in the Context Database UI, letting users tune search sensitivity on the fly. Changes persist to the active embedding preset immediately."
