docs: mark duplicated roadmap historical

[Pigbibi]

What changed

• replace the duplicated 2026-07-10 task-list roadmap with a historical pointer
• identify the canonical local P0-P6 architecture/current-state documents
• state that runtime/config facts and paper/shadow/live authority require fresh readback and separate human approval

Why

The copied task list was still named like a current roadmap and could be mistaken for current acceptance or execution order. Git history preserves the snapshot, so the maintained file can stay deletion-first and point operators to the canonical source instead of creating another roadmap fork.

Impact

Documentation only. No runtime settings, config, workflow, dependency, generated asset, strategy catalog, or deployment path changed. The deploy workflow path filters do not match this file.

Point operators to a shared canonical roadmap

For any operator reading this repository on GitHub or from a checkout other than this maintainer's Mac, the replacement canonical roadmap is inaccessible because it exists only under /Users/lisiyi/Documents/...; the current-state entry on the next line depends on that same directory. Since this commit removes the actionable roadmap and no other repository reference to these documents exists, those operators can no longer locate the stated source of truth. Use a durable shared URL or a repository-tracked path instead.
