feat: slskd reconnect guard in downloaders_reset, mass v2 sync

- downloaders_reset: connection check block before slskd API sections;
  triggers PUT /api/v0/server reconnect if disconnected, polls 60s,
  gates Stuck Searches and Dead Transfer Records on SLSKD_CONNECTED
- Sync all modified/new/deleted files from v2 refactor across Docker_Essentials,
  Media, Monitors, Partnership, Rsync, Tools, Transcodes, unRAID_Essentials,
  common.sh, master confs, and new Manual/README docs

 # ==============================================================================================

+# PURPOSE
+# ─────────────────────────────────────────────────────────────────────────────
 # Restores Claude Code's persistent data after an Unraid reboot and launches Claude.
+# Unraid's root filesystem lives in RAM — /root/.claude and /root/.local are wiped on
+# every reboot. This script symlinks both directories back to persistent appdata storage
+# before launching Claude, so memory, sessions, and settings survive across reboots.
 #
-# Unraid's root filesystem lives in RAM — /root/.claude and /root/.local are wiped on every
-# reboot. This script symlinks both directories back to persistent appdata storage before
-# launching Claude, so memory, sessions, and settings survive across reboots.
+# On first run with no existing persistent data, migrates from the current live locations:
+#   /root/.claude              → PERSIST_DIR/.claude            (memory, sessions, settings)
+#   /root/.local/share/claude  → PERSIST_DIR/local/share/claude (installed binaries)
+# Subsequent runs skip the migration and only create the symlinks.
 #
-# ── FIRST RUN ─────────────────────────────────────────────────────────────────────────────────
-# If persistent storage has no data yet, migrates from the current live locations:
-#   /root/.claude              → PERSIST_DIR/.claude     (memory, sessions, settings)
-#   /root/.local/share/claude  → PERSIST_DIR/local/share/claude  (installed binaries)
-# Subsequent runs skip the migration and just create the symlinks.
+# Standalone script — no common.sh dependency. Safe to run directly from terminal
+# or from array_started.sh.
+#
+# ==============================================================================================
+# RUNTIME MODES
+# ==============================================================================================
+#
+# claude_startup.sh
+#     Set up persistent symlinks and launch Claude.
+#
+# claude_startup.sh --setup
+#     Set up persistent symlinks only — do not launch Claude.
+#     Used by array_started.sh to prepare the environment on boot without
+#     immediately launching an interactive session.
 #
-# ── USAGE ─────────────────────────────────────────────────────────────────────────────────────
-#   claude_startup.sh           — set up persistent symlinks and launch Claude
-#   claude_startup.sh --setup   — set up only, do not launch (for array_started.sh use)
