feat(infra): grupo claude-fleet — FleetView TUI + orquestacion de Claudes

Sistema FleetView para centralizar la flota de procesos Claude Code vivos en una
sola ventana kitty + tmux (socket aislado -L fleet) con un panel TUI:

- list_claude_fleet (+ tipo claude_fleet): escanea ~/.claude/sessions + goals +
  runtime, valida procesos vivos (anti-PID-reciclado), join por sessionId.
- list_resumable_claudes (+ tipo resumable_claude): sesiones cerradas reanudables.
- wrappers tmux: tmux_new_claude_window (con --resume), tmux_swap_window_into_console
  (preserva ancho del sidebar), tmux_map_claude_panes.
- launch_kittyclaude: comando entrypoint; instala atajos alt+flechas/enter/n/0/k/r,
  mouse on, remain-on-exit off; fija el ancho del sidebar con hooks.
- docs/capabilities/claude-fleet.md + entrada en el INDEX.

Incluye ademas funciones datascience en progreso (excel/duckdb/postgres) y ajustes
varios de docs e infra de otra sesion, agrupados aqui para no perderlos.
