egutierrez 625569485f 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).

func FindUnusedFunctions(registryRoot string) ([]UnusedFunction, error)

Abre registry.db y retorna todas las funciones que no son referenciadas por ninguna otra funcion, app ni analisis. Util para detectar candidatas a deprecar o eliminar (fn doctor unused).

name	desc
registryRoot	Ruta absoluta a la raiz del registry (directorio que contiene registry.db).

Slice de UnusedFunction ordenado por AgeDays descendente (mas antigua primero). Cada entrada incluye ID, Name, Lang, Domain, Tags (JSON array como string) y AgeDays (dias desde updated_at).

true

solo fn_c queda huerfana con 2 funciones consumidas

launcher pipeline se excluye aunque nadie la use

error si registry.db no existe

functions/infra/find_unused_functions_test.go

functions/infra/find_unused_functions.go

Ejemplo

unused, err := FindUnusedFunctions("/home/lucas/fn_registry")
if err != nil {
    log.Fatal(err)
}
for _, u := range unused {
    fmt.Printf("%s (%s/%s) — %d dias sin uso\n", u.ID, u.Lang, u.Domain, u.AgeDays)
}

Notas

Recorre uses_functions en tres tablas: functions, apps y analysis.
Pipelines con tag launcher se excluyen: son endpoints intencionales aunque nadie los llame.
Pipelines sin tag launcher y sin consumidor SÍ aparecen — son candidatos igual.
Los tipos no se incluyen (eso es responsabilidad de otra funcion).
El campo Tags retornado es el JSON array crudo (ej. ["deprecated","core"]) para que el caller pueda filtrar por tag sin deserializar en esta funcion.
AgeDays se calcula con time.Parse(time.RFC3339, updated_at).
