Bolt-Era Record Collector Analysis

Lifted from `augment-it-bolt/specs/RecordCollector-Analysis.md`. Per-feature breakdown of the record-collector module in the bolt monolith. Worth cross-referencing against `Tanuj-Record-Collector-As-Built.md` — Tanuj later forked record-collector into its own Next.js repo, and the differences between this bolt-era version and Tanuj's split version are instructive about which patterns survived the federation experiment.
