chore(version): set dev to 4.1.0-dev

Keep dev ahead of the latest release tag (v4.0.8) with a pre-release marker so
public nodes running dev are unmistakable in /v2/health: `version` now reports
`4.1.0-dev` (sorts above 4.0.8, below any future 4.1.0 release) alongside the
exact `version_hash` (git HEAD). The 4.1.0 line reflects the additive opt-in
features merged since 4.0.8 (hot-first actions, get_transaction recent-first,
stream replay caps).
