v2.5.3

# Changelog

## New Features:

- **Remote Knowledge:** Added endpoints to support listing of remote contents via API. Enables uploading of content in S3 buckets via AgentOS

## Improvements:

- **PDF Reader:** Added `sanitize_content` parameter to `BasePDFReader` (enabled by default) that normalizes fragmented PDF text extraction — collapsing word-per-line artifacts while preserving paragraph breaks. Disable with `sanitize_content=False` for PDFs containing structured content like code or tables.
- **PDF Reader:** Added a `sanitize_content` parameter to `BasePDFReader` that normalizes extracted PDF text by collapsing excessive whitespace sequences into single spaces.

## Bug Fixes:

- **Knowledge Retriever:** Fix issue where`knowledge_retriever` ignored when `search_knowledge=True` enabled.
- **Claude:** Fixed streaming metrics double-count `input_tokens` for Anthropic models
- **Knowledge Search:** Fixed match include/exclude patterns against filename for directory scanning
- **Reasoning:** fixed `reasoning_content` duplication across reasoning steps.
- **Deepcopy on Agent/Team/Workflow:** fixed `deep_copy` fails for nested teams due to non-init dataclass fields.
- **HITL:** fixed HITL pause handlers silently dropping `session_state` changes in both **agent** and **team** modules.
- **Workflow Parallel Steps:** fixed race condition on `run_context.output_schema` in Parallel execution.
