Module lease 

Typed FCALL wrappers for lease management functions.

These wrap the Lua functions defined in lua/lease.lua. Each function uses the ff_function! macro to generate an async fn that builds KEYS/ARGV, calls FCALL, and parses the result.

Functions

ff_mark_lease_expired_if_due

Mark a lease as expired if it is actually due. Called by the lease expiry scanner.

ff_renew_lease

Renew an active lease. Extends expires_at by lease_ttl_ms.

ff_revoke_lease

Revoke an active lease (operator-initiated).
