fix: remove stale banned gen-v-connector V-lang recipe (#46)

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

## Removed

- The `gen-v-connector` Justfile recipe (the "Generate a V-lang
connector scaffold from the Groove manifest" recipe and its full body,
including the `connectors/v-*/` generator and embedded `main.v`
heredoc).

## Preserved

- No V-lang ban-enforcement asset was touched. The repo's own ban guard
(e.g. `scripts/check-no-vlang.sh`, estate-rules workflow,
`6a2/PLAYBOOK.a2ml`), where present, legitimately contains the
`gen-v-connector`/`vlang` string as a *detection* pattern and is left
intact.
- The legitimate `groove-setup` and `verify-template` recipes and the
`GROOVE & V-TRIPLE SETUP` section header (which they share) are
unchanged.

Justfile remains syntactically valid (`just --list` succeeds).
