feat: add dev tools, AI aliases, and improve zshrc documentation

This commit introduces several new features and improvements:

- **Adds Development Tools to `apps.sh`:** The `apps.sh` module now installs essential development tools, including `python`, `pip`, `nodejs`, `npm`, `uv`, and `nvm`.

- **Implements `.zshrc.local` for Private Variables:**
  - A `.zshrc.local.example` file has been added to serve as a template for users to securely store their private environment variables, such as API keys.
  - The main `.zshrc` file now sources `.zshrc.local` if it exists.

- **Adds AI Aliases to `.zshrc`:** A new section has been added to `.zshrc` with example aliases for interacting with command-line AI tools.

- **Improves `.zshrc` Documentation:** The `.zshrc` file has been thoroughly documented with comments in Spanish, explaining the purpose of each section. The title has also been updated and professionalized.

- **Fixes a Regression:** This commit restores the `ytm`, `ytv`, `ytls`, and SSH agent functions in `.zshrc` that were accidentally removed in a previous step.
