* feat(wasm): lazy schema injection on WASM tool errors

When a WASM tool returns an error (ToolReturnedError), call the module's
description() and schema() WIT exports and append them as a hint in the
error message. This lets the LLM retry with correct parameters without
us including large schemas in every request's tools array.

- Change ToolReturnedError from tuple to struct variant with hint field
- Add build_tool_hint() that calls WASM description()/schema() exports
- Cap description at 500 chars, schema at 3000 chars to limit context
- Hint flows automatically through Display → ToolError → ChatMessage

* fix: use floor_char_boundary for UTF-8 safe truncation in tool hints

Use existing crate::util::floor_char_boundary() to avoid panicking
when truncation lands mid-multibyte character. Addresses review
feedback on PR #638.
