fix(pack-verify): kill the --web child on failure too (same exit-skips-finally)

Browse source 
Re-review found the same process.exit()-skips-finally pattern in verifyWeb: a
failure during the --web phase goes through fail() → process.exit(1), skipping
its `finally { stop() }`, so the spawned web server was orphaned — left on the
port, where a later run could fetch a stale false-200 and mask a regression.

Track the live child in a module `webChild` and have fail() SIGTERM it before
exiting, alongside the workDir cleanup; stop() clears it on the success path.

Verified: a forced web-phase failure exits 1, retains the tarball, and leaves
no listener on the port (child killed, not orphaned).
