tooling: ps4-check.sh (one-command console evidence pull) + compress boundary rule

- scripts/ps4-check.sh: install.log/log.txt tails, status/diag/gen,
  staged PKG list, local-vs-remote payload size diff. Multi-file probe
  so a refused directory listing can't read as 'console offline'.

+# ps4-check.sh - one command to answer "what is the console actually running?".

+# artifacts against what the console has, so support questions resolve
+# without a multi-command FTP dance.

+# Env:   PS4_HOST (default 192.168.1.136)  PS4_PORT (2121)
