feat: add Sequence.any method and update docs, tests, and core source

Implement the `any` method on the Sequence class that returns true if any element passes the given predicate function. Update the core.wren library source, the C embedded source string in wren_core.c, and add comprehensive test files for normal usage, non-bool return values, and non-function argument error handling. Also fix a typo in the QA documentation and correct the initial account balance in the example.
