Bump ramdisk to 10G; add ramdisk_stop.sh; fix info→log typo in common.sh

Browse Source 
host1.conf: HOST1_RAMDISK_SIZE 8G→10G, WARN_GB 6.8→8.5, LOW_GB 5.5→7.
ramdisk_stop.sh: new Tools/ script — redirects symlink to SSD before unmount
  so Emby keeps writing during maintenance, auto-falls back to lazy umount
  when only directory handles are open (no active writes).
common.sh: fix `info` call at line 595 (undefined) → `log`.
Tools docs: added ramdisk_stop.sh to README table, categories, diagram, and Manual.

# Ramdisk size ceiling — tmpfs only uses RAM actually needed, not the full size upfront.
# Real-world: 9 streams peaked at ~5.5GB — 8G gives comfortable headroom on 128GB RAM.

# Usage thresholds — coupled to HOST1_RAMDISK_SIZE, adjust all three together if size changes.
# Hysteresis gap (6.8 - 5.5 = 1.3GB) prevents flip-flop between ramdisk and SSD.
HOST1_RAMDISK_WARN_GB=6.8 # flip to SSD when ramdisk usage reaches this

# SSD fallback path — where transcodes land when ramdisk exceeds HOST1_RAMDISK_WARN_GB.
# Must be on cache pool — array disks too slow for active transcode writes.
