[Bug]: ```Circuit.transpile``` doesn't support $\text{RZZ}$ gates while the rest of ```transpiler.py``` does.

[emlynsg]

Describe the bug
transpiler.py currently supports the common gate operations in Graphix, including the $\text{RZZ}$ gate. However, the method Circuit.transpile does not and raises an error.

To Reproduce
Steps to reproduce the behavior:

import numpy as np
from graphix import Circuit
circuit = Circuit(2, instr=[instruction.RZZ(0, 1, np.pi / 4)])
pattern = circuit.transpile().pattern

Expected behavior
The gate should be managed in the transpiler in an equivalent way to other gates.

Environment (please complete the following information):

• OS: Ubuntu
• Python version: 3.13.7

Additional context
Problem to be avoided completely by upcoming transpiler reworking.
