refactor(monorepo): reorganización lógica + renames + SDDs + split CHANGELOG

Reorganización física de crates/:
- core/ (mezclaba 6 propósitos) se divide en protocol/, init/, runtime/, compat/
- shared/ (3 crates) se redistribuye en protocol/ e init/
- lapaloma (sub-módulo de ui_engine) se promueve a modules/pineal/

Renames de proyectos:
- shipote → shuma (runtime de sandboxes)
- nouser → akasha (explorador de Mónadas)
- yahweh → nahual (motor GPUI, antes ui_engine/)
- lapaloma → pineal (data-viz agnóstica)

Fraccionamiento UI → core agnóstico:
- vista-core (DeckState + snap, 175 LOC, 5 tests verdes)
- barra-core (Task + render_html + sanitize, 90 LOC, 5 tests verdes)
- vista-web y barra-web ahora son thin DOM bindings

Documentación nueva:
- 16 SDDs por subdirectorio (≤80 LOC c/u): protocol/init/runtime/compat
  + 10 módulos + apps/
- docs/STATUS.md con cifras reales por proyecto
- docs/ROADMAP.md con plan a finalización (6 hitos, ~6-8 semanas)
- CHANGELOG.md particionado en docs/changelog/<proyecto>.md (7 buckets)

Automatización:
- scripts/reorg.py — script idempotente que: git mv directorios, renombra
  package names, recomputa path = refs, reescribe imports rust, actualiza
  workspace Cargo.toml. Soporta --dry-run.
- scripts/split-changelog.py — particiona CHANGELOG por componente.

Validación:
- cargo check --workspace pasa (124 crates + 2 nuevos cores).
- 10 tests adicionales (5 en vista-core + 5 en barra-core) verdes.
