Feature: add Rising/velocity sorting for ranked posts

good-karmarequested to merge
rising into develop

Adds a new rising sort type that ranks posts by rate of engagement change rather than absolute engagement. Unlike trending (total rshares + time decay) or hot (same with faster decay), rising measures rshares velocity - how fast a post is gaining votes right now.

How it works

  • A new sc_rising score is computed every 200 blocks (~10 min) by comparing current vote_rshares against a previous snapshot
  • Formula: (current_rshares - snapshot_rshares) / hours_since_snapshot
  • Only posts from the last 7 days are candidates
  • New posts get a baseline-only first pass (score = 0) to absorb automated curation trail votes before measuring real velocity
