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). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

## Ejemplo
|
|
|
|
```go
|
|
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)`.
