Provide a supported way to clear run_size.

Preserving run_size when an update omits it is intentional patch behavior. However, UpdateTowerfileRequest says omission lets Tower apply its default, and no MCP clear operation exists. Because Option<String> maps both omission and JSON null to None, the handler cannot clear an existing value.

Add an explicit clear flag or operation. If clearing is intentionally unsupported, change the request documentation to say that omission preserves the current value.

Suggested clear flag 
-    /// basic.medium, basic.large. Omit to let Tower apply its default.
+    /// basic.medium, basic.large. Omit to preserve the current value.
     run_size: Option<String>,
+    /// Remove run_size and let Tower apply its default.
+    #[serde(default)]
+    clear_run_size: bool,
...

Review comment at @crates/tower-cmd/src/mcp.rs around lines 1045 - 1047:
Add an explicit clear_run_size flag to UpdateTowerfileRequest and its tool
description, then update the run_size handling to set it to None when clearing
is requested; reject requests that provide both run_size and clear_run_size.
Change the run_size documentation to clarify that omission preserves the current
value.
