fix(tools): default Claude tool type when missing

Browse Source 
Strict Anthropic-compatible gateways (e.g. MiniMax) reject Claude-format
requests with HTTP 400 when tools[].type is missing. Normalize each
missing/falsy tools[].type to "custom" before dispatch when the final
request format is Claude. Built-in tool types (computer_use, bash,
web_search_*) are passed through untouched.

// Default `type: "custom"` on Claude-format tools that arrive without one.
// Anthropic's Claude tool schema requires `type` to be explicitly set; strict gateways
// (e.g., MiniMax Anthropic-compatible endpoint, error 2013) reject legacy payloads that
// omit it with HTTP 400. Tools that already carry a truthy `type` (e.g., `computer_use`,
// `bash`, `web_search_20250305`) are passed through untouched.
//
// Spread order matters: `{ ...tool, type: "custom" }` (spread first, override last)
// ensures that falsy `type` values (null, undefined, "") in the original tool don't
// overwrite the default. `{ type: "custom", ...tool }` would let `type: null` survive.
