New SettingsMutation set: the per-frame settings mutators
(handle_volume_keys → record_window_geometry_changes →
persist_window_geometry_after_debounce) run as a deterministic chain
ordered before GameMutation, so every reader already after GameMutation
observes the current frame's settings transitively. The four readers
outside that ordering (modal enter-speed chain, focus-ring pulse, HUD
avatar, and the game plugin's pre-mutation chain) are ordered after the
set explicitly.
SettingsResource ambiguities: 21 → 0. Baseline ratchets 198 → 171.

Second phase of #118 for settings_plugin: the 2,857-line mod.rs becomes
four focused submodules along existing system boundaries —
mod.rs 561 types, markers, SettingsButton, plugin build, persistence
input.rs 632 button/hotkey handlers, focus attachment, scrolling
updates.rs 495 per-frame value-text updater systems + label helpers
ui.rs 1,231 spawn_settings_panel + row builders + thumbnails
Moved items are pub(super); mod.rs glob-imports the submodules so
system registration and tests keep their bare names. No behaviour
change; all 29 settings tests pass unchanged.
