refactor(naming): A1 — ente→arje, vista→revista, pluma→fana

Rename batch de la Fase A del PLAN_MACRO:
- 25 crates ente-* → arje-* (protocol/init/runtime/compat). El linaje
  arje (init Linux) queda con prefijo coherente.
- vista → revista (revista-core + revista-web).
- pluma → fana (fana-md + fana-md-reader-web). fana absorbe el linaje
  markdown de pluma; será el writer DAG editor (prioridad alta).

Cambios:
- git mv de 29 crate dirs + 2 SDDs
- package/lib/bin names + path refs + imports .rs reescritos
- workspace Cargo.toml + comentarios de sección
- SDDs de init/runtime/compat/protocol actualizados a arje-
- SDD de revista + SDD de fana (reescrito: writer DAG editor)
- docs/STATUS.md, ROADMAP.md, PLAN_MACRO.md, arje-boot.md,
  arje-replace-systemd.md actualizados
- docs/changelog/akasha.md → chasqui.md

scripts/rename-fase-a.py idempotente (--dry-run soportado).
cargo check --workspace verde.
