Module payload_fixer 

LLM-JSON autofixer — ports payload_fixer.py.

Parses a raw JSON string from an LLM, applying tolerant fixes:

1. normalize smart (curly) quotes to straight quotes,
2. on parse failure, strip trailing commas and retry,
3. wrap a bare top-level object into a one-element list.

Returns Ok(Vec<Value>) on success, or an A2uiError (Parse for serde failures, Validation for a non-list/non-object top level).

Functions
