Two follow-ups bundled into a single commit:
- docs/superpowers/specs/2026-05-15-janitorial-cleanup.md collects
the "do later" small TODOs that surfaced across the recent idmap
+ consolidation work: dead cake-related artifacts, obsolete
static systemd units in deploy/files/, the bubblewrap→systemd-run
doc drift, stale gameserver-side idmap binds on un-checked
instances, calendar reminder for SM 1.13 stable. Each item is
small and self-contained.
- docs/l4d2-server-cvar-reference.md captures the research from
the early-session L4D2 cvar deep-dive: tickrate sweet spots,
nb_update_frequency cheat-protection + sm_cvar workaround,
cvars that don't exist in L4D2 (net_maxcleartime,
z_resolve_zombie_collision_multiplier per RCON probe), recommended
plugins, MetaMod/SourceMod branch tracking, and the empirically-
verified idmap-propagation-through-rebind kernel-6.12 quirk.
Reference material, not a spec — lives at docs/ root.
