Introduce a complete `.env.example` covering Telegram, AI provider,
proactive messaging, web search, and vision settings so new users can
bootstrap configuration without reading the source.
Rework README.md with a feature list, project structure, and variable
reference tables; restructure DEPLOY.md with a table of contents,
prerequisites, and env var tables; update RULES.md to declare English
as the interface and documentation language and to document the
`iniciar.sh` entry script. Also add docstrings to schedule and web
search helpers and rename `schedule_data` to `schedule_answers` for
consistency with the other wizard state variables.
