fix(require-command): avoid unsupported regex lookahead in dev-branch check

The `regex` crate does not support negative lookahead, so the ported
`^dev-(?!main$|master$|trunk$|latest$)` pattern panicked at runtime on
any `require` invocation that reached version-selection. Replace it
with equivalent hand-written string logic per docs/dev/regex-porting.md.
