JonKazama-Hellion 74bcb91b65 feat(themes): auto-reload active custom theme on disk change
When the user edits their active custom theme JSON in an external editor
and saves, the change now propagates to HellionChat within ~1 second
without re-selecting the theme in the picker.

RefreshActiveIfStale runs from Plugin.Draw on every frame but the actual
File.GetLastWriteTimeUtc stat is 1Hz-throttled -- 60fps would otherwise
mean 3600 stats/min, more on Wine. Built-in themes short-circuit on the
IsBuiltIn check; custom themes without a captured source path (Switch
fell to default) short-circuit on the null check.

Switch() now captures the source path of custom themes via an out-param
on LoadCustomBySlug, which now reverse-looks-up against the existing
_customCache (no re-parse, no extra disk IO). Plugin.LoadAsync warms the
cache via AllCustom() once before the first Switch so a Config.Theme
pointing at a custom slug does not fall through to the built-in default
on a cold registry.

Switch's lookup order is now built-in-first to match Get(slug), so a
user-authored JSON that declares a built-in slug is consistently
ignored in both code paths.

Pure-helper ThemeStampDiff isolates the stamp-diff rules for the
Build-Suite (covers DateTime.MinValue hold-the-line semantics).

// Pure stale-check for the v1.4.8 B2 theme-auto-refresh-on-active path.
// Lives in a free helper class so the Build-Suite can exercise the diff
// rules without instantiating ThemeRegistry (which touches the Dalamud
// log proxy and the filesystem). The rules:
// - DateTime.MinValue on the current stat means we could not read the
// file -- hold the last known good (return false).
// - Equal stamps mean no change since we last saw it.
// - Any other difference, including the first observation where lastSeen
// is MinValue, counts as stale and triggers a reload.
