Flag "equal to" where "equal is used as a verb"

I just heard "to equal to" in a YouTube video. Googling shows that it's a common class of error.

"Equal" is both an adjective and a verb but "to" is only used with the adjective:
- ✅ A equals B
- ✅ A is equal to B
- ❌ A equals to B

Here's some examples from GitHub:
- ` ` should **equal to** `' '` (one space)
- the local_frame will **equal to** the initial frame
- one cycle would **equal to** 0.27ns that would mean a branch miss would be 4.05ns
- update the variable to **equal to** sum of internal cluster distances
- repeat `posterior::split_chains` on the fitted object until these **equal to** the number of cores wanted
- I am wondering here, why does the `num_qps_per_rank` need to **equal to** the number of local experts?
- Which does **equal to** 0.

No file, test, or entry point is named in the issue. Start by locating the existing grammar-rule implementation and its test conventions, then verify that the rule flags verb uses such as “equals to” while leaving adjective uses such as “is equal to” valid.
