feat: 4 tools nuevas + browser_list enriquecido

Tools nuevas (wrappers finos sobre funciones del registry functions/browser):
- page_collect_console  -> cdp_collect_console (console + exceptions + log, snapshot)
- page_pdf              -> cdp_print_pdf (Page.printToPDF a archivo)
- dom_select_option     -> cdp_select_option (<select> por value/texto + input/change)
- dom_set_files         -> cdp_set_file_input (subir archivos a <input type=file>)

browser_list ahora enriquece cada master con CDP con pages (nº de page targets),
active_title y active_url via GET /json (best-effort: si el puerto no responde
los campos quedan a cero y el listado de procesos no falla).

Total tools: 46 -> 50.
