v1.0.0-beta.5

Fifth beta — feature-complete for v1.0.0, heading into release-candidate hardening.

Added

• Plugin marketplace + developer program: browse and install signed plugins by name; per-developer scoped certificates verified at install time.
• Per-account TLS / private CA: nodes obtain leaf certificates signed by the account's own root, with the customer approving each node's signing request.
• Wallet + auto-renewal billing: prepaid account balance with opt-in auto-pay, so a license renews on its expiry day without manual payment.

Fixed

• Hardware-bound licensing: clearer fail-closed message when fewer than two firmware identifiers are readable (bare-metal only).
• Marketplace: self-hosted plugin index pulls now retry with backoff instead of failing the whole sync on one unreachable developer host.

Performance

• Lower control-plane chatter during steady-state clustering (heartbeat coalescing).
