v2.19.6

What's Changed

Two independent hosted-AI chat fixes (PR #49):

Configurable max_tool_rounds for hosted AI

• New config key chat_max_tool_rounds (Optional[int], None = use the server default), sent as max_tool_rounds on the chat request and clamped server-side. Lets you raise the agentic tool-loop cap for long investigations.
• Deliberately a new key rather than reusing chat_max_tool_iterations (which governs only the local/user-keyed provider loop and is persisted as 10 in existing configs).
• Omitted from the request body when unset, so servers that don't support it ignore the key harmlessly.

Dangerous-tool confirm modal no longer silently denies

• Pressing Enter with an empty or wrong value on the typed-confirm "RUN" modal previously dismissed it as a denial with no feedback. Now the only ways to deny are Escape or Cancel.
• An exact RUN (tolerant of surrounding whitespace, still case-sensitive) confirms; any other submitted value keeps the modal open with an inline hint.
