chore(release): bump version to 2.7.3

Ships the fingerprints baseline fix (e7af9ae): every install since
2.7.0 had a broken Phase 7 step 2.5 that threw TypeError on the first
/understand run and left fingerprints.json empty/missing, which made
every subsequent auto-update escalate to FULL_UPDATE. This release
replaces the LLM-written script with a bundled build-fingerprints.mjs
and reorders Phase 7 to write fingerprints before meta.json.

Anyone upgrading from 2.7.0–2.7.2 should re-run /understand --full
to regenerate a valid baseline.
