I am submitting a new Community Plugin

• I attest that I have done my best to deliver a high-quality plugin, am proud of the code I have written, and would recommend it to others. I commit to maintaining the plugin and being responsive to bug reports. If I am no longer able to maintain it, I will make reasonable efforts to find a successor maintainer or withdraw the plugin from the directory.

/skip
The UI text already follows sentence case as described in the documentation.
Only the first word of each sentence is capitalized, and proper nouns such as
“Go”, “Go Playground”, and acronyms like “URL” are intentionally preserved.
Lowercasing these proper nouns would be incorrect and reduce clarity.
