v2.7.3

# Changelog

## New Features:

- **Valkey**:
    - Added `ValkeyDb` as a fast in-memory database for agents, teams, and workflows. See [Docs](https://docs.agno.com/database/providers/valkey/overview)
    - Added a `ValkeyDB` vector store with vector and keyword search. See [Docs](https://docs.agno.com/knowledge/vector-stores/valkey/overview)
- **Redmine Tools**: Added `RedmineTools` to manage issues, comments, and time logs in Redmine, an open source project management tool.
- **TokenLab**: Added `TokenLab` as a new OpenAI-compatible model provider.

## Improvements:

- **Session Context**: Skip a redundant model call when saving session context.
- **AG-UI**: Extended human-in-the-loop confirmation, input, and feedback to AG-UI.
- **User Memory & Profile**: More reliable memory and profile extraction from conversations.
- **MCP Tools**:
    - Surface a clean error when an MCP server becomes unreachable.
    - Support tools that respond with only `structuredContent`.

## Bug Fixes:

- **DoclingReader**: Accept local file-path strings.
- **JSONReader**: Honor `chunk=False` when reading JSON documents.
- **PDFReader:**
    - Fix incorrect page number interpretation for single page pdf’s.
    - Auto-try a blank password for encrypted PDFs.
- **Structured Outputs**: Reliably parse responses whose field values contain braces.
- **File & Coding Tools**: Keep search and listing contained to the configured root.
- **Antigravity**: Prevent symlinked files from escaping the agent directory.
- **Cassandra**: Derive the vector dimension from the configured embedder.
- **Mistral**: Add `frequency_penalty`, `presence_penalty`, and `stop`, and keep zero-valued params like `temperature=0`.
- **YouTools**: Fix failing searches and add region, language, and freshness filters.
- **Workflow Metrics**: Include metrics on `WorkflowCompletedEvent`.
- **Timer**: Fix `Timer.elapsed` for very fast operations.
