The vue-tui:request-reload hot handler awaited extractBundle with no
try/catch. extractBundle throws ("No JS bundle found in Vite memoryFiles")
on a transient/broken build, and Vite's hot event emitter does not catch
async handler rejections — so the rejection escaped as an unhandledRejection
that could take down the whole dev process. The crash-respawn interval right
below already guards extractBundle for the same reason.
Extract the reload logic into a testable, module-scoped handleReloadRequest()
(also folding in the acceptReloads startup guard via a shouldAccept predicate)
and wrap the extract/restart work in try/catch: on failure, log via
logger.error and KEEP the previous bundle (no setBundlePath/restart), so a
momentarily broken build no longer kills the dev server. The inline
server.hot.on handler now delegates to it.
