- Renamed `forum/experiments` to `forum/poc-g1` to designate generation 1. - Created `forum/poc-g2` and a new `lab.ts` runner. - Non-destructively migrated `dag_engine_poc.ts`, `git_storage_poc.ts`, `merkle_diff_poc.ts`, and `frontmatter_poc.ts` to `poc-g2`. - Upgraded migrated PoCs to utilize actual production-ready tools (e.g. `std/yaml` parsing and isolated `Deno.Command` Git repos) per blueprint constraints.
