sightsound: new FLM NPU sight+sound service on XDNA2 (gemma4-it:e4b)

New Dankclaw service frank-default-sightsound: FLM 1.0.1 serving the
Gemma4-E4B-IT-NPU2 pack (vision+audio+reasoning, 131072 ctx) on the XDNA2
NPU at port 52626. Model choice rationale: gemma4-it is the only NPU2 model
family with BOTH image and audio towers; the uncensored candidate qwythos:9b
is text-only, so sight+sound wins over uncensored here.

Deployer wiring: planner maps env/unit/serve files to the new service name;
deploy-remote gains deploy_llm_sightsound (relink + daemon-reload + enable +
restart + health gate on /v1/version — FLM has no /health route). Unlike the
retired frank-default-npu relink-only path, this unit is boot-enabled.
