fix(land-and-deploy,gen): auto-merge diagnosis + CRLF-stable generation

Two small hardenings: land-and-deploy Step 4 no longer misdiagnoses a
failed `gh pr merge --auto` as a permissions problem when the real cause is
the merge-method mismatch the command names; and gen-skill-docs normalizes
CRLF at the template entry point so Windows checkouts with autocrlf produce
byte-identical generated output to CI instead of silently skipping the
\n-anchored transforms.
