feat(tools): include tool arguments in events

[bassamsdata]

Description

This PR extends tool-related events to include the tool arguments in their payload. The change is additive and does not affect existing behavior.

Benefits / Use cases

• Enables extensions such as fs-monitor.nvim to access relevant metadata (e.g. file paths) when tools operate on files.
• Improves observability of tool execution by exposing command arguments, enabling filtering, targeted notifications, and safety checks (for example, detecting potentially dangerous commands executed via cmd_runner).

Example event output:

ToolStarted │ bufnr: 131 │ id: 5844143 │ cmd: find . -maxdepth 4 -name "*.rs" │ tool: cmd_runner

ToolStarted │ bufnr: 131 │ id: 1017944 │ filepath: hive/src/config/loader.rs │ explanation: Refactoring configuration loading to improve error handling and reduce duplicate parsing logic │ tool: insert_edit_into_file

Thank you
