- Add specific rate limit type (requests/tokens/max_parallel_requests) to error message
- Include current limit value for better context
- Display reset time in human-readable format
- Handle negative remaining values gracefully by showing 0 instead
- Add reset_at header with timestamp for programmatic use
Fixes issue where rate limit errors were ambiguous about which type of limit
was exceeded and when the limit would reset.

* feat: add Vertex AI support for file content retrieval
- Extended `custom_llm_provider` to include "vertex_ai" in `afile_content` function.
- Implemented file content retrieval logic for Vertex AI in `VertexAIFilesHandler`.
- Added helper method to extract bucket and object from URL-encoded file_id.
- Created comprehensive unit and integration tests for Vertex AI file handling.
- Updated transformation logic to ensure compatibility with Vertex AI file responses.
* fix: update Vertex AI file transformation logic
- Modified the transformation logic in `VertexAIFilesConfig` to return a newline-separated JSON string for batch JSONL files instead of a array if JSON strings.
* fix: enhance Vertex AI output handling in transformation logic
- Updated the transformation logic in `VertexAIBatchTransformation` to utilize the new `OutputInfo` TypedDict for retrieving the GCS output directory.
- Added `OutputInfo` class to type definitions for better structure and clarity in Vertex AI responses.
* fix: avoid NoneType AttributeError when extracting tags
I've been running into this error:
```
21:47:08 - LiteLLM:ERROR: litellm_logging.py:2396 - LiteLLM.LoggingError: [Non-Blocking] Exception occurred while success logging Traceback (most recent call last):

)
File "/usr/lib/python3.13/site-packages/litellm/router_strategy/budget_limiter.py", line 396, in async_log_success_event

File "/usr/lib/python3.13/site-packages/litellm/router_strategy/tag_based_routing.py", line 144, in _get_tags_from_request_kwargs
return _metadata.get("tags", [])
^^^^^^^^^^^^^
AttributeError: 'NoneType' object has no attribute 'get'
```
This makes the function more resilient without resorting to try catch.
* add tests

- Add response_modalities configuration to request format
- Fix response parsing to use camelCase 'inlineData' instead of snake_case 'inline_data'
- Update test to validate proper request format and response parsing
- All existing Gemini image generation tests pass
- Reverted GEMINI_2_5_FLASH_IMAGE_PREVIEW_MODEL constant usage
- Made endpoint selection conditional for gemini-2.5-flash-image-preview only
- Preserved existing Imagen models functionality with :predict endpoint
- Fixed potential breaking change that would affect 6 other Gemini image models
