Tool annotations

Every tool exposes accurate MCP hint annotations:

readOnlyHint — true for read tools (threads.list, messages.read_history, kg.find_entity, …)
destructiveHint — true for delete tools (messages.delete, widgets.delete, …)
openWorldHint — true for tools that touch third-party APIs (messages.send, web.search, contacts.sync, …)
idempotentHint — derived from read-only/delete-by-id semantics

See server.json for the registry manifest and gemini-extension.json for Gemini CLI integration.
