…data Add new optional columns to participants.tsv for richer age and life cycle metadata: - birthdate/birthtime: Date and time of birth - deathdate/deathtime: Date and time of death - age_category: Life cycle stage (embryo, neonate, infant, juvenile, adult, etc.) These columns support animal studies and developmental research where precise life cycle information is important. Human subjects should anonymize or omit sensitive fields like birthdate. Life cycle stage enums are inspired by UBERON ontology. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Summary
This PR adds age-related columns and metadata to
participants.tsvto better support animal data and clarify age specifications across species. Key additions include:life_cycle_stagecolumn with enums based on UBERON ontology (embryo, neonate, juvenile, adult, etc.)AgeReferencemetadata field forparticipants.jsonto specify what theagevalue is relative to (birth, fertilization, LMP_startdate)birthdate/birthtimeanddeathdate/deathtimeoptional columnsAgeReferencewhenagecolumn is presentThis is a continuation of #1839, which was accidentally closed due to a force-push.
Please refer to #1839 for the full discussion history and review comments. Since the commits were too many and too conflicting to do a rebase, only the final edits with a single commit was made to restore from this point. A backup with the history of the commits is here.
