Your Name 16bc6685f8 fix: honor --dry-run across install phases; repair repo conventions and doc drift
- spawn() now respects DRY_RUN, install.sh exports it to child phases, and
  postinstall.sh wraps every user-home mutation in run() — '--dry-run' no
  longer runs apt/install/clone or edits dotfiles for real
- gen-docs.sh chmods regenerated files to 644 (mktemp mv left them at 0600)
- make check now syntax-checks apps/, entertainment/, features/, templates/
- .gitignore protects config/authorized_keys + config/rclone.conf; drop the
  tracked empty authorized_keys and the stray 6 MB session file
- pos-system-health --send prints 'sent:' only when a platform sender exists,
  otherwise warns on stderr (notify_send is silent-fail)
- standardize sourced libs (no shebang); refresh AGENT_Context/DEV/APPS/SCRIPTS
  doc drift: notify.sh in lib lists, pos-health systemd units, tsui, scripts/,
  INTERACTIVE_CMDS list, entertainment scheduler (systemd timers only)

# lib/notify.sh — optional MULTI-PLATFORM alerting helper. Self-contained by
# design: defines ONLY notify_send() + notify_platforms() (plus internal
# helpers) so it can be sourced by tools that define their own log/warn/err
# (e.g. pos-system-firewall) without clobbering.
#
# Usage (opt-in — source it, do NOT auto-load from common.sh):
# source "$(dirname "$0")/../lib/notify.sh" 2>/dev/null || source "$(dirname "$0")/notify.sh"
# notify_send "Backup completed: $ARCHIVE"
# notify_send "**disk full**" --markdown
#
# Platform routing — ~/.config/linux_post_install/notify.env:
# NOTIFY_PLATFORM=telegram,matrix
# Comma-separated = send to every listed platform (default: telegram).
#
# Sender contract — each platform is a bin/pos-communication-<platform> tool
# that MUST implement:
# pos-communication-<platform> send <value> [--markdown]
# (exit 0 on delivery; non-zero on failure)
# To add a platform (e.g. Matrix/Synapse), add `bin/pos-communication-matrix`
# implementing that interface and put `matrix` in NOTIFY_PLATFORM.
#
# Silent-fails per platform: a missing sender or a failed send only warns and
# never changes the caller's exit code.
CONFIG_DIR="${XDG_CONFIG_HOME:-$HOME/.config}/linux_post_install"
