Add tool for clearing console logs to isolate errors related to specific actions

[siiXth]

Currently, it is difficult for an agent to determine which Unity console errors are related to a specific action (e.g., script modification or MCP tool execution).

Suggested workflow:

1. Call console-clear-logs
2. Perform an action (e.g., modify a script or execute an MCP tool)
3. Call console-get-logs to retrieve only the errors produced by that action

At the moment, it seems that the only available workaround is to track the start time of the action and use the lastMinutes parameter in console-get-logs, but this approach is indirect and unnecessarily complicated.

Adding a dedicated console-clear-logs tool (or another mechanism to scope logs to a specific action) would make it much easier for agents to accurately associate errors with the changes they just performed.
