Reorganize: llm/scripts -> scripts (LLM serve scripts, units, env tunables)

The LLM fleet serve scripts, systemd units, env tunables, and bench
harnesses join the deploy scripts. The vllmScripts deploy.sh is
removed here; its functionality is folded into the unified
scripts/deploy.sh in a follow-up commit.

bench-spec-stack.sh gains the executable bit (required by the
scripts_syntax test seam).

-# deploy.sh - Deploy the vllmScripts repo to a target and restart its service.
-#
-# This script implements the second half of the git deployment workflow from
-# AGENTS.md. It assumes the local changes are committed and pushed, then:
-#   1. Pulls the repo on the target
-#   2. Symlinks the systemd unit
-#   3. Reloads systemd and restarts the service
-#   4. Waits for the health endpoint and reports status
-#
-# Sudo: set FRANK_SUDO_PW so remote sudo reads the password from stdin
-# (`sudo -S`). The passwordless restart helpers installed for the retired
-# topology are obsolete and must not be used.
-#
-# Usage:
-#   ./deploy.sh <target> [--dry-run]
-#   FRANK_SUDO_PW=... ./deploy.sh <target>
-#
-# Targets (2026-08-18 topology):
-#   dankserver - llama.cpp Qwen3.6-35B-A3B Q6_K_P (frank-default-small.service, port 7770)
-#   dankclaw   - CIRU ROCmFPX llama.cpp Qwen3.8-27B (frank-default-large.service, port 52625)
