NubsCarson 019f8d614f fix(mcp): expose MCP tool input parameters to the agent ...

MCP server tools were presented to the agent with only their name and a
truncated description: get_tool_descriptions_for_prompt() emitted
"- name: description" and get_all_tools() dropped input_schema entirely.
On the fenced-block tool path (used by Ollama models), the agent could
not see a tool's declared inputs and guessed argument names from the
description alone, so tool calls failed (issue #2509). MCP inspector
showed the schemas fine, confirming the loss was on our side.

- get_all_tools() now carries each tool's input_schema.
- get_tool_descriptions_for_prompt() renders a compact args hint
  (parameter names, coarse types, required-ness) via a new
  _format_mcp_params() helper, matching the "Args (JSON): {...}" style
  the built-in tool descriptions already use.

Fixes #2509
