ASO Rankings Check (krankie)

Pull keyword rankings with krankie instead of Astro MCP, compare against the previous check, and save a dated rankings file to the Obsidian vault.

This is the no-subscription replacement for asc-aso-rankings. krankie is MIT-licensed, stores history in local SQLite, and reads ranks from the public App Store search API. The trade-off vs Astro: krankie reports rank position only - no popularity or difficulty scores, and tracks the top 200 (Astro tracked top 250).

Architecture: VPS is the source of truth

• VPS (lobster@openclawtail) runs krankie under a daily cron (krankie cron), so the SQLite DB there holds the continuous day-over-day history. This is canonical.
• MacBook also has krankie installed for ad-hoc local peeks, but its DB only has data from whenever it was last run - do not use it for the historical comparison.
• The vault is bidirectionally synced between the VPS (/home/lobster/vault) and the MacBook (/Users/antonnovoselov/Documents/Vault), so a report written on either side appears on both.

Because the VPS holds the history and the previous_rank/rank_change columns krankie computes between checks, run the check + report on the VPS.
