Symbols mode should include trailing colons

Noticed this:

symbex '*alias*' -f ../llm/llm/__init__.py -sn

def get_models_with_aliases() -> List[?]

def get_embedding_models_with_aliases() -> List[?]

def get_embedding_model_aliases() -> Dict[(str, EmbeddingModel)]

def get_model_aliases() -> Dict[(str, Model)]

def set_alias(alias, model_id_or_alias)

def remove_alias(alias)

Those signatures would be valid Python if they had a : at the end.

Even more so with docstrings:

symbex '*alias*' -f ../llm/llm/__init__.py -ns --docs --documented

def set_alias(alias, model_id_or_alias)
    "Set an alias to point to the specified model."

def remove_alias(alias)
    "Remove an alias."

After the fix:

def set_alias(alias, model_id_or_alias):
    "Set an alias to point to the specified model."

def remove_alias(alias):
    "Remove an alias."
