v0.17.4

v0.17.4

Fix: every optional tool parameter was advertised to a Claude Max subscription turn as a required string. memory_search's ids (list[str] | None) arrived at the handler as the literal string "[]", failing pydantic validation on every call; every OTHER optional filter (date_after, date_before, alias, ...) arrived populated with an empty-string placeholder instead of being omitted, degrading conversation_search/chunk_search results (found live, same prod conversation as v0.17.3, 019f6cf5-073a-7b50-bd44-721efb0c7b90).

• _SubscriptionChatModel._wrap_langchain_tool (packages/models/src/threetears/models/providers/_claude_cli.py). Pydantic renders an X | None field as anyOf: [{type: X}, {type: null}] with no top-level type key; the schema-to-SDK conversion's naive prop.get("type", "string") silently defaulted every such field to string. Separately, handing the SDK a bare {name: type} map (rather than a full JSON Schema) makes its own schema builder mark every key required, forcing the model to invent placeholder values for filters it had nothing to fill in. _wrap_langchain_tool now builds the full {type: object, properties, required} schema itself, resolving each property's real type and copying required verbatim from the source tool schema.

Fix: NameMangledToolProxy never forwarded config to a delegate that requires it. A real 3tears builtin tool (a StructuredTool built by to_langchain_tool, e.g. threetears.calculator) raised TypeError: StructuredTool._arun() missing 1 required keyword-only argument: 'config' the instant it was actually invoked through this proxy, on EVERY provider that uses it (anthropic.py, openrouter.py, and the Claude Max subscription backend) -- not a claude-cli-specific bug, a pre-existing gap in shared name-translation infrastructure, found live testing the fix above.

• NameMangledToolProxy._arun/_run (packages/models/src/threetears/models/tool_name_translation.py). BaseTool.arun/run only forward config to _arun/_run when that method's OWN signature declares a RunnableConfig-typed parameter -- the proxy never declared one, so it never received a config to forward, and its body called the delegate's _arun/_run directly with none. Fixed by declaring config/run_manager on the proxy's own methods, then forwarding to the delegate only if its own signature wants them.

Both fixes verified live against a real Claude Max subscription subprocess call (real customer credential, real dotted 3tears builtin tools, real correct results) and via a real browser session in metallm.
