Add 'return' and 'strict' to /reasoning-parse

- Add 'return' arg to `/reasoning-parse` to decide whether to return the reasoning, or the content without reasoning. Defaulting to reasoning.
- Add 'strict' arg to `/reasoning-parse` to decide whether the reasoning block has to be at the beginning of the provided message or not. Defaulting to true.
- Update parsing of all reasoning (even the auto parse one) to be strict by default - meaning the regex block has to be at the beginning (excluding whitespaces)
