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.

//! ente-systemd1-compat: shim de `org.freedesktop.systemd1.Manager`.

//!
|

//! Centro de control que `systemctl` consulta. Sin esto, `systemctl list-units`
|
||||
//! falla con `Failed to connect to bus` aunque el sistema funcione.
|
||||
//!
|
||||
//! Mapeo: cada Ente vivo del fractal aparece como una "unit" cuyo nombre es
|
||||
//! `<label>.service`. Estados:
|
||||
//! - `loaded` siempre (porque está en el grafo)
|
||||
//! - `active` si tiene PID o es Wasm corriendo, `inactive` si está virtual
|
||||
//! - sub_state: `running`/`exited`/`virtual`
|
||||
//!
|
||||
//! Métodos cubiertos del subset que `systemctl` típicamente llama al boot:
|
||||
//! - ListUnits (basis de `systemctl list-units`)
|
||||
//! - GetUnit / GetUnitByPID (object-path lookup; no servimos métodos del unit)
|
||||
//! - StartUnit / StopUnit / RestartUnit (forwardea al bus interno)
|
||||
//! - Subscribe / Unsubscribe (no-op)
|
||||
//! - Reload (no-op — Cards inmutables)
|

//! - ListUnitFiles (vacío)
