Every test helper says what it is for

[SirLouen]

Closes #97

What

Every helper function and method in a test file now carries a one line docblock naming what it does, closing a gap of 173 across 49 files. Test functions still carry none, which is the convention every one of the 1199 already follows. A .coderabbit.yaml states both conventions to the reviewer, along with the rules on comments in Go and SQL and on fuzzy translations, so the same findings stop arriving each round.

Nothing but comments changed in the test files. The diff adds 173 comment lines and no code line at all.

Why

The split was 386 helpers documented against 173 bare, which reads as an accident rather than a choice, and a reader meeting a bare seedStoredMedia had to read its body to learn that it seeds a message, attaches pending media and then marks that media stored. Each new line was written from the body rather than the name, so it says what the helper actually does instead of restating its identifier.

Test functions are the opposite case and stay as they are. Their names already carry the intent, a docblock limited to WHAT could only repeat the name, and the absence of one is what keeps the pressure on the name where it belongs. The Go tooling agrees, since no test doc comment is ever rendered anywhere.

The config exists because the same two requests arrived in four separate review rounds. Encoding a convention once is cheaper than declining it every time, and it lets a genuine finding stand out instead of being buried under a preference the repository has already settled.

Testing Instructions

1. Open plugins/whatsapp/download_internal_test.go and read the line above seedStoredMedia. Compare it with the body and confirm it names all three steps rather than restating the function name. Do the same for seedMessage in plugins/whatsapp/media_internal_test.go and testDatabaseURL in cmd/alphone/main_test.go.
2. Confirm no test function gained a comment:

   git diff origin/main..HEAD -- '*_test.go' | grep -B1 "^+func Test"
   

   It prints nothing, since every added line sits above a helper.
3. Confirm the diff carries no code change:

   git diff -U0 origin/main..HEAD -- '*_test.go' | grep "^+" | grep -v "^+++" | grep -v "^+\s*//"
   

   It prints nothing.
4. Confirm the config is valid and comment free, since this repository allows no YAML comments:

   python3 -c "import yaml; print(len(yaml.safe_load(open('.coderabbit.yaml'))['reviews']['path_instructions']), 'path entries')"
   grep -n '#' .coderabbit.yaml
   

   The first prints 4 path entries and the second prints nothing.
5. Read this pull request's own automated review when it arrives. It is the live check on the config: no comment should ask for a doc comment on a function whose name begins with Test.
