[py] querychat 0.6.1

New features

• Added stream cancellation support. A stop button now appears during LLM streaming, allowing users to cancel in-progress responses by clicking it or pressing Escape. Cancellation is enabled by default and can be disabled via enable_cancel=False in the UI. (#241)

Improvements

• The tools parameter now uses "filter" as the preferred name (instead of "update") for the dashboard-filtering tool group. The default is now ("filter", "query"). The legacy name "update" is still accepted everywhere. (#222)
• Suggestion prompts now render more reliably as interactive cards across LLM providers. (#236, #238)
• Bumped minimum ggsql version to >=0.3.2. (#233)
