[vite-plugin] Local observability on by default costs 4-10x dev request latency, and the cost grows with app size
### Versions `@cloudflare/vite-plugin` 1.50.0 · vite 8.2.0 · wrangler 4.118.0 · node 25.5.0 · bun 1.3.13 · Windows 11 x64 ### Summary 1.50.0 enabled local observability capture by default. On a four-file worker this takes dev request latency from ~40 ms to ~178 ms. On a real app it goes from ~28 ms to ~296 ms. `X_LOCAL_OBSERVABILITY=false` restores it fully. This is a report on the default, not a request to remove the feature. ### Measurements Bisect on a four-file worker whose entire body is `export default { fetc…
