delete_active_file tool has invalid schema for openai-codex (openclaw)

[locoblacbelt]

Bug Description

The delete_active_file tool is registered with an input schema of {"type": "object"} with no properties field. Strict providers (e.g. openai-codex) reject this with: Invalid schema for function 'obsidian__delete_active_file': In context=(), object schema missing properties.
Fix is to add "properties": {} to the input schema definition for that tool.
