v2.6.3

# Changelog

## New Features 
- WorkspaceContextProvider (#7709): Project-aware context provider for repository roots, backed by the read-only Workspace toolkit instead of generic FileTools. Centralizes local filesystem exclude patterns so both FileTools and Workspace skip .context, .venvs, and other agent/dependency/build noise by default. FilesystemContextProvider now accepts exclude_patterns for explicit opt-out/customization.         

## Improvements

- SlackContextProvider (#7710): Simplified provider and inlined SlackTools construction. Removed for_bot_read(), for_assistant_search(), and for_write() factory methods in favor of explicit flags. Added opt-in enable_workspace_search parameter. Tools are now self-documenting via SlackTools, removing runtime agent switching.                                                                                               

## Bug Fixes

  - **Slack:**
    - Gracefully fall back to public channels when the `groups:read` scope is missing.                                                        
    - Restore Slack read instruction override and tighten briefing guidance.                                                                  
    - Expose Slack update in agent mode; agent mode returns query-only.
