v2.9.1

Fixed

• Honker handle now actually opens — v2.9.0 reported caps.honker = true but getHonker() silently returned null, leaving the queue/cron/pub-sub features dormant. Root cause: both the plugin and honker-bun's open() called the once-per-process Database.setCustomSQLite(), so honker-bun threw "SQLite already loaded". The plugin now neutralises further calls after loading the custom SQLite, so honker-bun reuses the already-active extension-enabled SQLite. Verified end-to-end (enqueue → claim → ack, pub-sub notify, scheduler register).
