[codex] add L1 research inventory

[FlowmemoryAI]

Summary

• adds docs/L1_RESEARCH_INVENTORY.md with the GitHub-sourced Noesis / Flow Chain, Rootflow, FlowCodec, and older AI-L1 research inventory
• updates CURRENT_STATE and ROADMAP so future agents treat Noesis as external research, not approved production L1 implementation
• includes scoped starter prompts for chain, crypto, and review agents

Validation

• git diff --check HEAD~1..HEAD

Notes

• Docs-only change.
• No product implementation, tokenomics, production deployment, or L1 build work is included.

HQ review note, 2026-05-13: docs-only research inventory remains useful, but it touches CURRENT_STATE and ROADMAP. Rebase/refresh against current main plus the new full-L1 milestone/issues #99-#108 before merge. Merge order: before or alongside research decision issue #106 if refreshed; otherwise after #106 lands concrete decision records. No duplicate subsystem or production-claim issue seen in the current PR summary.

HQ review blocker, 2026-05-14: before this older draft can be reconsidered, please refresh the PR body with linked issue/research scope, allowed folders, forbidden folders, worktree path, and exact checks run with results. Because this PR touches docs/CURRENT_STATE.md and docs/ROADMAP.md, it also needs a rebase/refresh against the current FlowChain private/local testnet source-of-truth docs before merge.
