patch

Fix client-executed provider tools (Memory, Text Editor, Computer Use, Bash) which were unusable on the wire.

• makeResponse (and the streaming equivalents) now map a provider tool_use wire name (e.g. "memory") back to the tool's custom name (e.g. "AnthropicMemory") that the toolkit is keyed by, instead of raising ToolNotFoundError.
• AnthropicTool.MemoryCreateCommand now includes the required file_text field, so a create command no longer drops the file body.
• Optional parameters on client-executed provider tools now use Schema.optionalKey instead of Schema.optional, which the Anthropic codec rejected with "Unsupported AST Undefined": Memory/TextEditor view_range, ComputerUse coordinate, and Bash restart.

Closes #2615.
