Prune auto-research presentation layers

[huangruiteng]

Summary

• remove auto-research board, acceptance packet, artifact packet, public-claim boundary, showcase/frontstage projection paths from the main auto-research surface
• move the visible demo supervisor into a thin module backed by the generic multi-agent TUI runner and pane-local A2A tick
• keep the kernel focused on frontier, evidence graph, worker-turn/worker-loop, and compact live evidence

Dashboard route smoke was not run in this worktree because apps/dashboard has no local tsc/node_modules installed (sh: tsc: command not found).

Self-review findings: none.

Product/architecture judgment: this PR intentionally removes the auto-research presentation stack from the kernel path: board, acceptance packet, artifact packet, public-claim boundary, showcase/frontstage projection, and related smokes/routes. The remaining path is the intended lightweight shape: generic multi-agent TUI runner, pane-local A2A tick/worker-turn, and compact frontier/evidence graph state. Product surfaces can be rebuilt later as consumers of public-safe evidence graph/frontier state instead of living inside auto-research core.

Main risk: broad cleanup touches CLI/docs/smokes/dashboard route wiring. Risk is mitigated by focused auto-research smokes, py_compile, public/private scan, diff check, and the GitHub Frontstage Pages build passing. Dashboard route smoke could not be run locally because apps/dashboard has no local tsc/node_modules installed.
