Kayos 2d4c2163a9 mcp: add reference_script_path arg to bypass MCP large-string transport bug
Caught 2026-05-07: hex strings passed to MCP tool args > ~4500 chars
get a 1-byte truncation + structural rearrangement somewhere between
Claude Code and aldabra's stdio reader. Pallas + aldabra-core's
hex_decode are byte-clean (verified via crates/aldabra-dao/examples/
repro_script_corruption.rs); the corruption is purely in the
JSON-RPC-over-stdio transport layer.

Workaround: accept reference_script_path that points at a file
inside the aldabra container. Caller docker-cp's the hex file in,
passes the path via MCP arg, aldabra reads bytes locally — no
large strings cross the JSON-RPC wire.

Applies to wallet_send + wallet_send_unsigned. wallet_plutus_mint_*
tools still ride the hex-string path (small policies only, < 4500
chars). When we hit a Plutus policy that needs the workaround, port
the same pattern.
