1.0.0-alpha10: render-tree collector + CwvPanelWeight tightening Second content release on the alpha7 collector contract. Same shape as alpha9: implements async-decoration (Shape 2) plus panel-contribution (Shape 4), opt-in via config, zero overhead when disabled. - RenderTreeInstrumentor captures response-level cache metadata: tag count, context count, hottest tag prefix. - RenderTreeCollector ships per-request stats to AsyncContextStore at terminate and renders a Render-tree correlation panel showing CWV metrics bucketed by tag count. - BeaconStorage::correlateByRenderTreeSize aggregation buckets beacons by tag count (0-25 / 26-100 / 101-300 / 301-1000 / 1001+). Opt-in via render_tree_instrumentation_enabled (default FALSE). Default installs pay zero overhead. cwv_update_10007 lands the key on existing installs. Also tightens CwvPanelWeight constants: adds CORRELATION = 200 midband, bumps TIME_SERIES from 200 to 300, repositions the correlation panels (per-route, backend cache, render-tree) into the new band. Fixes the layout discrepancy spotted in alpha9 field testing where AGGREGATION + 100 collided with TIME_SERIES. CwvPanelWeight constants are due to freeze at beta1; alpha10 is the last release where they can move.
