Houmgaor 5c2fde5cfd feat(rengoku): validate and log Hunting Road config on startup ...

Port ECD encryption/decryption from ReFrontier (C#) and FrontierTextHandler
(Python) into common/decryption. The cipher uses a 32-bit LCG key stream with
an 8-round Feistel-like nibble transformation and CFB chaining; all six key
sets are supported, key 4 being the default for all MHF files.

On startup, loadRengokuBinary now decrypts (ECD) and decompresses (JKR) the
binary to validate pointer bounds and entry counts, then logs a structured
summary (floor counts, spawn table counts, unique monster IDs). Failures are
non-fatal — the encrypted blob is still cached and served to clients unchanged,
preserving existing behaviour. Closes #173.
