Python 3.14 changed asyncio.get_event_loop() to raise RuntimeError when
no running event loop exists instead of silently creating one. This broke
all async code paths that relied on get_event_loop().
Changes:
- Replace asyncio.get_event_loop() with asyncio.get_running_loop() in all
async contexts across crewai core and crewai-tools
- Update requires-python from '<3.14' to '<3.15' in all pyproject.toml files
- Add comprehensive tests for Python 3.14 async compatibility
- Regenerate uv.lock for the updated version constraint
Closes#5109

pypdf <6.7.4 has multiple DoS vulnerabilities via crafted PDF streams
(FlateDecode, LZWDecode, RunLengthDecode, XFA, TreeObject, outlines).
Only basic PdfReader/PdfWriter APIs are used in crewai-files, none of
which changed in the 5.0 or 6.0 breaking releases.
- add input_files parameter to Crew.kickoff(), Flow.kickoff(), Task, and Agent.kickoff()
- add provider-specific file uploaders for OpenAI, Anthropic, Gemini, and Bedrock
- add file type detection, constraint validation, and automatic format conversion
- add URL file source support for multimodal content
- add streaming uploads for large files
- add prompt caching support for Anthropic
- add OpenAI Responses API support
