fix: remove stale banned gen-v-connector V-lang recipe (#10)

Held consumer sweep following rsr-template-repo PR #22, which removed
the
stale `gen-v-connector` V-lang recipe from the template. This repo
carried a
pre-PR#22 copy of that recipe.

## What was removed

- The banned `gen-v-connector` Justfile recipe and its V-lang connector
scaffold body (the `connectors/v-<service>/src/main.v` generator and its
  "Generate a V-lang connector scaffold" comment header).

## What was preserved

- The repo's own V-lang ban-enforcement assets (e.g.
  `scripts/check-no-vlang.sh`, `.github/workflows/estate-rules.yml`,
`6a2/PLAYBOOK.a2ml`) are intentionally left untouched — they contain the
  banned string only as a *detection pattern* and must stay.

The Justfile remains syntactically valid (`just --list` passes).
