Speed up runspace and tab initialization (#4793)

* Add startup performance tracing * Lazy initialize non-default tabs * Render install app entries incrementally * Defer and cache toggle status checks * Clean up runspace invocation ownership * Defer GUI runspace pool startup * Defer status taskbar asset rendering * Record final speed verification * Fix deferred install render timer callback * Add dispatcher smoke coverage for install rendering * Replace install render timer with dispatcher callbacks * Gate performance tracing behind compile switch * Clean up analyzer warnings in speed changes * Speed up runspace and tab initialization
