aws-patch v1.10.3

Added

• GRUB default boot entry mismatch detection (RHEL-family, where
  grubby is available). A kernel can be genuinely, correctly
  installed -- real boot files present, not a stale database entry --
  and still not be what a reboot would actually load, if GRUB's own
  default boot entry was never updated to point at it (normally
  automatic via the kernel package's own post-install scriptlets, but
  can fail to complete after an interrupted transaction). Previously
  aws-patch had no way to detect this before rebooting; a --reboot
  run would silently restart into the exact same kernel that was already
  running, with nothing in the summary to reveal why.
  • lib/kernel.sh: new _kernel_grub_default_matches() -- read-only
    (grubby --default-kernel) comparison against the kernel version a
    reboot is expected to load. Sets KERNEL_BOOT_DEFAULT_MISMATCH.
    Unverifiable systems (no grubby -- most Debian/Ubuntu installs)
    are left unflagged rather than guessed at by parsing grub.cfg,
    which would risk false positives blocking legitimate reboots.
  • lib/summary.sh: reports Reboot Required: GRUB DEFAULT MISMATCH
    distinctly from both a plain YES and a STALE ENTRY.
  • aws-patch.sh: handle_reboot() skips the no-op reboot (even with
    --reboot/--yes) and logs the exact grubby --set-default
    command needed, instead of rebooting into nothing changing.
  • docs/troubleshooting.md: new "GRUB default not updated to the new
    kernel" section with the full fix.
  • This is read-only inspection only -- lib/kernel.sh still never
    writes to GRUB or changes the default boot entry itself; the file's
    header comment was clarified to make that distinction explicit.
• New test coverage in tests/run_tests.sh (== GRUB default boot entry mismatch ==): mismatch detected, correct-default not falsely
  flagged, and grubby-unavailable never blocks a reboot.
