Add log_filter: pluggable per-unit output filter subprocess
Each unit can specify log_filter: <path> pointing to any executable
that reads stdin and writes filtered output to stdout. The daemon
spawns it once at startup (and on SIGHUP), pipes raw log data through
it before ring-buffering and broadcasting to attached clients.
filter.c handles spawn (fork/exec with pipes), per-chunk apply
(write + poll with 250ms timeout, pass-through on silence/timeout),
and stop (SIGTERM + fd cleanup). Filters are stopped and restarted
cleanly on SIGHUP alongside log_tail.
Bundled filters in filters/:
source.py — TF2, GMod: strips server_cvar/stuck/path_goal spam,
strips the L MM/DD/YYYY - HH:MM:SS: prefix
minecraft.py — vanilla/Paper/Spigot: strips keepAlive, autosave,
internal class logs, strips [HH:MM:SS] [thread] prefix
terraria.py — vanilla/tModLoader: strips blank lines and mod
loading noise during startup
Any executable reading stdin/writing stdout works as a custom filter.
