[TASK]: Create a GoLLM task for converting (cleaned/styled) LaTeX to SymPy string, replacing parse_latex

[liunelson]

Describe the task
Update the GoLLM task that clean LaTeX equations to also convert them to SymPy string, replacing sympy.parse_latex().

Task Items

• How can we consume SymPy strings to be parsed by SymPy for MIRA consumption #5817
• Update the GoLLM task to include the finding from ⏫ #5818

Goal
SymPy's parse_latex is prone to inserting () into equations and MIRA tends to take (...) expressions as rate laws for templates. This results in wrong template models. For example, "SIR" models end up not having a single controlled conversion from S to I with rate law b*S*I; instead, they have two templates (a controlled production and controlled degradation).
