massive update. Master conf split, now modular with a load sceriprt to drive all configs to scripts. with unraid scpecific safeguard tests , and improved standardized ux. including dynamic host detect, who am i who else it there. EVERY SINGLE SCRIPT UPDATED. DEBATING THAT THIS IS ACUALLY V2

# ----------------------------- PHP-FPM Max Children Script ------------------------------------
# -----------------------------------------------------------------------------------------------
# Persistently sets PHP-FPM pm.max_children on unRAID.
# Config file path and max children value are set in Master.conf.
# Supports --dry-run to preview what would be changed without making changes.
# -----------------------------------------------------------------------------------------------
# ==============================================================================================
# ============================= PHP-FPM Max Children ===========================================
# ==============================================================================================
# Persistently sets PHP-FPM pm.max_children on unRAID to prevent WebGUI slowdowns.
# Run once at array start via ARRAY_START_SCRIPTS in master.conf.
# Idempotent — completely silent when value is already correct.
#
# ── WHY THIS EXISTS ───────────────────────────────────────────────────────────────────────────
# unRAID's WebGUI runs through PHP-FPM. The default pm.max_children is very low (4-8).
# Under load — multiple users, Docker operations, heavy dashboard usage — all PHP workers
# saturate and new requests queue. The WebGUI becomes slow or unresponsive.
#
# pm.max_children controls how many PHP worker processes can run simultaneously.
# Raising it allows the WebGUI to handle more concurrent requests without queuing.
# Too high: wastes RAM. Too low: WebGUI slowdowns.
# PHP_MAX_CHILDREN=250 is appropriate for 128GB — ~2MB per worker = ~500MB total.
#
# ── WHY IDEMPOTENT ────────────────────────────────────────────────────────────────────────────
# This runs at every array start. If the value is already correct there is nothing to do —
# no config write, no PHP-FPM restart. Restarting PHP-FPM unnecessarily disrupts active
# WebGUI sessions and is annoying on every boot.
#
# ── APPLY SEQUENCE ────────────────────────────────────────────────────────────────────────────
# 1. Read current pm.max_children from PHP_CONF
# 2. If already at target → exit silently (idempotent)
# 3. Verify sed pattern matches before writing
# 4. Apply sed replacement
# 5. Restart PHP-FPM via rc.php-fpm
# 6. Verify PHP-FPM process running after restart
# 7. Verify config file reflects target value
#
# ── SAFEGUARDS ────────────────────────────────────────────────────────────────────────────────
# Root check — writing to system config requires root
# acquire_lock — prevents concurrent runs at array start
# Idempotent check — only restarts PHP-FPM when value actually changes
# Pattern match check — verifies sed found pm.max_children before writing
# Process verify — confirms PHP-FPM running after restart
# Config verify — reads back config to confirm value applied
# validate_unraid — notify validated before use
# Silent on correct — runs every boot, no noise when already set ✅
#
# ── CONFIGURATION (master.conf) ───────────────────────────────────────────────────────────────
# PHP_MAX_CHILDREN — target pm.max_children value (default 250)
# PHP_CONF — path to PHP-FPM www.conf (default /etc/php83/php-fpm.d/www.conf)
#
# ── USAGE ─────────────────────────────────────────────────────────────────────────────────────
# php_fpm_max_children.sh — normal run (idempotent)
# php_fpm_max_children.sh --dry-run — show what would change
# php_fpm_max_children.sh --status — show current vs target and process state
# php_fpm_max_children.sh --log — verbose output
