fix: pin kind 11998 in the indexable-content golden and make it CRLF-proof

The golden test's KINDS list was missing the new heartbeat kind, and the
comparison read the golden raw — on Windows CI (autocrlf checkout) every
internal CRLF counted as a diff, failing the suite with a full-table
ComparisonFailure. Adds 11998 as a pinned <not searchable> row (a heartbeat
is a machine signal: no indexable content, per the NIP-50 eligibility
policy), normalizes CRLF in the comparison, and forces LF for *.golden in
.gitattributes so checkouts can never break it. No reindex needed: nothing
is indexed for this kind.
