Add a link-issue command that creates GitHub's Development reference
and verifies both sides. Keep Closes in descriptions for context, but
make the API link the source of truth, including for merged PRs.
Add tests for successful links, missing verification, output, and
failures. Update the PR workflow memories and create-pr skill to use
the command.

Move all development tools from tools/ to scripts/ for consistency.
Rename lint/fmt/check-fmt to lint-clj/fmt-clj/check-fmt-clj to clarify
they target Clojure specifically. Remove unused scripts (attach-opencode,
start-opencode, start-opencode-server) and the backport-commit skill.
Update all internal references across .serena/, AGENTS.md, and
CONTRIBUTING.md to point to the new script locations. Simplify
CONTRIBUTING.md by delegating module-specific fmt/lint instructions
to the respective serena memories.
