Eric Traut 55922b7984 Include installer stderr in daemon update failures (#50499) ...

## Why

Daemon updates discard installer stderr, leaving failed installs with only an exit status and no installer diagnostics.

## What changed

Capture the last 2 KiB of installer stderr and append it to errors when the installer exits unsuccessfully. Drain stderr concurrently and wait at most one second after failure so subprocesses holding the pipe open cannot delay error reporting indefinitely. Keep captured details within the manual update response limit, and configure PowerShell output as UTF-8 to preserve non-ASCII diagnostics.

## Testing

Add coverage for stderr tail truncation, bounded draining when a subprocess keeps stderr open, and manual update responses containing heavily escaped diagnostics. Extend the Windows installer test to check non-ASCII error text.
