Add weed/command/pushdown.go that parses CLI flags (-filer, -ip, -port, -trust, -dev.connector_trusted_ack), assembles a daemon.Config, and calls daemon.Run. Default port 18888 is unused elsewhere in the SeaweedFS port table and is far enough above the filer/master/volume ports to be unsurprising in operations. Long help spells out the two trust modes and points the operator at PARQUET_PUSHDOWN_DESIGN.md and PARQUET_PUSHDOWN_DEV_PLAN.md for context. Register cmdPushdown in weed/command/command.go's Commands list so "weed pushdown" appears in the top-level help. The command is gated "<WIP>" until later milestones land actual pruning behavior.
