add filter "home-assistant-analytics"

Home Assistant stores a signed token authenticating analytics snapshot submissions as data.submission_identifier in .storage/core.analytics. Replace it with "…" via jq, if not null.

Requires jq >= 1.7 to keep floats like snapshot_submission_time unchanged. Since smudge is a no-op, a checkout restores "…", and Home Assistant obtains a new token on its next submission.
