docs: indoor flicker/void root cause (decomp + live cdb) + 3-part fix plan handoff

Browse source 
Diagnosis session: the indoor bluish void + grey/texture flicker is visibility metastability at cell boundaries, not a missing flood (R1's per-cell DrawInside is built; the cellar seals). Confirmed by named-retail decomp AND a live cdb capture of retail (viewer_cell rock-stable: clean monotonic transitions, zero oscillation across 4916 samples). Retail stays stable via boom stability + a 0.2mm viewer-cell dead-zone + clip-space portal clipping; acdream diverges on all three. Handoff documents the root cause, the cdb evidence, and the prioritized 3-part retail-faithful fix (boom stability -> dead-zone -> w-space clip) with decomp anchors + a planning/implementation kickoff prompt. Adds the reusable retail viewer-cell cdb capture script and the superseding CLAUDE.md banner.

* Retail viewer-cell stability capture (2026-06-05)
* Confirms whether retail SmartBox viewer_cell flips at a portal boundary
* or stays stable. Samples viewer.objcell_id ~6/sec to avoid lagging retail.
* Auto-detaches after 6000 hits via .detach (cdb ignores qd inside bp actions)
* NOTE never put a semicolon inside a comment line, it splits into a command
