hestia: replacing the Keemple smart-home cloud

hestia reimplements the Keemple gateway's cleartext 0x7e-framed protocol for local smart-home control. A specification derived from observed LAN traffic covers framing, TLVs, handshakes, device commands and reports. The Python server operates as a decoding proxy or a standalone cloud replacement, with a web dashboard and local automation.
