⬆️ Upgrade: bump @picgo/bump-version to 3.0.0

3.0.0 ships as ESM and renamed the configs it exposes to consumers, so
the cz-customizable and commitlint paths gain their .cjs extensions.

It also stopped shipping contributor tooling as runtime dependencies,
which this repo was relying on: @commitlint/cli reached the commitlint
script only as a transitive dependency of bump-version 2, so the upgrade
would have removed the binary the commit-msg hook needs. It is now a
direct devDependency.

Drops the "husky" field, which has been dead config since c84d542 moved
this repo to husky 9 — v9 reads .husky/ and ignores it entirely. The
circular-dependency check it used to declare has been unhooked ever
since, so lint:dpdm moves to .husky/pre-commit where it actually runs.
Confirmed it both passes on the current tree and fails on a deliberately
introduced cycle, so it is a real gate rather than a no-op.
