egutierrez 2a3d780347 feat(doctor): add fn doctor CLI + 14 functions for system management

Adds `fn doctor` read-only diagnostic command with subcommands artefacts,
services, sync, uses-functions, unused, and --json flag for agents.
Each subcommand wraps a registry function in functions/infra/.

New functions:
- artefact_doctor, services_status, pc_locations_drift,
  audit_uses_functions, find_unused_functions (Go diagnostics)
- backup_sqlite_db, rotate_backups, wait_for_http, wait_for_port,
  port_kill, tail_journal, pre_commit_hook_install (bash utilities)
- notify_telegram (Go HTTP)
- backup_all pipeline (tag launcher)

Plus prior session leftovers (scan_secrets_in_dirty, append_diary_entry,
git utilities, http_session_cookie_middleware, compile/full-git pipelines).

Fixes pc_locations_drift filepath.Join bug with absolute dir_path.
Documents fn doctor in CLAUDE.md, .claude/rules/fn_doctor.md (rule 23),
docs/architecture.md, CHANGELOG.md (2026-05-07), and diary entry.

First fn doctor uses-functions run found drift in 7/12 apps (deuda
para sincronizar app.md con imports reales).

functions/infra/services_status.go

name	desc
registryRoot	Ruta absoluta al directorio raiz del registry (donde vive registry.db)

Slice de ServiceStatus con estado systemd, puerto y pc_id por cada app con tag 'service'. Error si no se puede abrir registry.db.

Ejemplo

statuses, err := ServicesStatus("/home/lucas/fn_registry")
if err != nil {
    log.Fatal(err)
}
for _, s := range statuses {
    fmt.Printf("%s  unit=%s  port=%d  listening=%v\n",
        s.Name, s.UnitActive, s.Port, s.PortListening)
}

Notas

UnitName se asume <name>.service. Si la app usa otro nombre, el estado sera not-installed.
La heuristica de puerto busca el primer entero en [1024, 65535] en notes o description. Si la app menciona varios numeros, toma el primero que encaje. Puede fallar si notes contiene IDs numericos antes que el puerto real.
UnitActive intenta systemctl --user is-active primero; si el unit no se encuentra, reintenta con scope de sistema. Valores posibles: active, inactive, failed, not-installed, unknown.
PortListening hace un dial TCP a 127.0.0.1:<Port> con timeout 500ms. Solo aplica si Port > 0.
HostMatch lee ~/.fn_pc — primer linea no vacia no comentada.
