```
- **g4f/providers/helper.py**
- Add `render_messages()` to normalise message contents that are lists of blocks.
- **g4f/Provider/Blackbox.py**
- Import `get_har_files` and `render_messages`.
- Replace manual walk of `get_cookies_dir()` with `get_har_files()` in `_find_session_in_har`.
- Simplify session‑parsing loop and exception logging; drop permissions check.
- Build `current_messages` with `render_messages(messages)` instead of raw list.
- **g4f/Provider/Cloudflare.py**
- Swap `to_string` import for `render_messages`.
- Add `"impersonate": "chrome"` to default `_args`.
- Construct `data["messages"]` with `render_messages(messages)` and inline `"parts"`; remove `to_string()` calls.
- Move `cache_file` write outside inner `try` to always save arguments.
- **g4f/Provider/Copilot.py**
- Defer `yield conversation` until after `conversation` is created when `return_conversation` is requested.
- **g4f/Provider/openai/har_file.py**
- Break out of `os.walk` after first directory in `get_har_files()` to avoid deep traversal.
- **g4f/api/__init__.py**
- Use `config.conversation` directly and set `return_conversation` when present.
- **g4f/client/__init__.py**
- Pass `conversation` to both `ChatCompletionChunk.model_construct()` and `ChatCompletion.model_construct()`.
- **g4f/client/stubs.py**
- Import `field_serializer` (with stub fallback).
- Add serializers for `conversation` (objects and dicts) and for `content` fields.
- Extend model constructors to accept/propagate `conversation`.
- **g4f/cookies.py**
- Insert ".huggingface.co" into `DOMAINS` list.
- Stop recursive directory walk in `read_cookie_files()` with early `break`.
- **g4f/gui/client/background.html**
- Reorder error‑handling branches; reset `errorImage` in `onload`.
- Revise `skipRefresh` logic and random image URL building.
- **g4f/gui/server/backend_api.py**
- Add `self.match_files` cache for repeated image searches.
- Use `safe_search` for sanitised term matching and `min` comparison.
- Limit walk to one directory level; support deterministic random selection via `random` query param.
- **Miscellaneous**
- Update imports where `render_messages` replaces `to_string`.
- Ensure all modified providers iterate messages through `render_messages` for consistent formatting.
