Fixes #2461

What's Changed

• Updates @playcanvas/inspector to 0.5.0.
• The Launch menu's Profiler option now opens the Inspector on its Performance tab, recording from before the first frame, so the Startup entry and the Loading section cover the load. It still launches with ?profile=true and the profiler engine build, so old URLs and the MCP profiler option keep working.
• Removes the Launch page's own profiler (src/launch/tools/, its styles, and the tools:frame:field:add / tools:frame:field:value events). Custom fields now go through app.stats.user, shown in the Inspector's Counters section.
• Like the Inspector option, Profiler needs Engine 2.23 or later. On older engines the app runs without a panel and logs a warning; the tooltip says so.
• The Inspector has no option to open a tab yet, so the Launch page switches to Performance through its private _setTab. If that changes upstream, recording still starts and the panel opens on another tab.

Known: the Inspector logs ResizeObserver loop completed with undelivered notifications once to the launch page's error console when it opens on the Performance tab. This also happens with the Inspector option alone when Performance was the last tab used, and is to be fixed in the Inspector.

User Manual: playcanvas/developer-site#1339, replacing the Profiler page with Inspector Performance.

Smoke Test

1. Tick Profiler in the Launch menu and launch a project on Engine 2.23 or later. The Inspector opens on Performance, already recording, with a Startup entry for the load.
2. Open a saved launch URL with ?profile=true. The same Inspector view opens.
3. Untick Profiler, tick Inspector and launch. The Inspector opens, not recording, and the old profiler overlay does not appear.
4. Launch a project on an engine older than 2.23 with Profiler ticked. The app runs without a panel.
