set_category_budget
Set the amount budgeted (“Assigned”) in a category for a month, after the user confirms.
The amount is absolute, in currency units, not a change. The result gives the amount before and after; undo_operation restores the previous one. Confirmation works as for apply_categories.

Section titled “Fouten”Category {category_id} is not in this plan: use a category_id from get_category_balances.month must be 'current' or the first day of a month as YYYY-MM-01, got '{month}'.This client cannot ask the user to confirm, and AVENIR_MCP_REQUIRE_ELICITATION=1 forbids confirmation codes: nothing was changed. Use a client that supports MCP elicitation, or unset the variable.This confirmation code is unknown, expired, already used, or was issued for different changes. Call again without confirmation to get a new preview.Confirmation codes are disabled (AVENIR_MCP_REQUIRE_ELICITATION=1): call again without confirmation, and the user answers in the client.The plan changed between the preview and the answer.
