Opal is neither a sedimentary, igneous, nor metamorphic rock. It is actually a mineraloid composed of hydrated silica that is formed from silica-rich solutions at low temperature, often found in sedimentary rocks like sandstone or volcanic areas.

Does a rock go through the complete rock cycle by changing from igneous rock to sedimentary to metamorphic?

Yes, it can. However, an igneous rock can change to a metamorphic rock skipping sedimentary: the tectonic plates can push igneous rock deep into the ground, forming metamorphic rock. Sedimentary can form metamorphic, metamorphic can form magma or lava by melting and/or erupting and then turn into igneous. Igneous forms sedimentary with erosion, deposition compaction, and cementation.

Is breccia a sedimentary metamorphic or igneous rock?

Yes. In the rock cycle, any sedimentary rock can be transformed into a metamorphic rock due to deep burial where the rock is changed by the earth's high temperature and pressure, an exposure to a plutonic intrusion, where rocks such as granite are formed, or any other process where heat and pressure alter the composition, appearance, and classification of a rock. An igneous rock can turn into a metamorphic rock or a sedimentary rock. A metamorphic rock can turn into an igneous rock or a sedimentary rock, and a sedimentary rock can turn into an igneous rock or a metamorphic rock.
