feat(apps): Añadir Drivers de Video para Intel (#13)

* 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.

* feat: improve keyring UX and icon manager flow

This commit introduces two main improvements to the user experience:

1.  **Refactors the Icon Manager for Non-Interactive Installation:**
    - The `icon_manager.sh` module can now be run in a non-interactive mode.
    - The "Install All" process has been updated to use this non-interactive mode, which installs the default icon theme without pausing the script or requiring user input.

2.  **Improves the GNOME Keyring Workflow:**
    - The script no longer errors out if the GNOME Keyring agent is not immediately available after installation.
    - Instead, a clear summary message is now displayed at the end of the "Install All" process, instructing the user to log out and back in, and then run the SSH key synchronization module separately. This provides a much smoother and more intuitive user experience.

* fix: improve GNOME Keyring socket detection

This commit fixes a bug in the `ssh-keyring.sh` module where the GNOME Keyring socket could not be found after a system reboot.

The script now explicitly determines the user's UID to construct the correct path to the socket, instead of relying on the potentially unreliable `$UID` environment variable. This makes the socket detection more robust, especially when the script is run with `sudo`.

* fix: improve GNOME Keyring socket detection

This commit fixes a bug in the `ssh-keyring.sh` module where the GNOME Keyring socket could not be found after a system reboot.

The script now uses the `logname` command to reliably determine the user's UID and construct the correct path to the socket, instead of relying on environment variables that can be unreliable when the script is run with `sudo`. This makes the socket detection more robust.

* feat: Añadir nuevas herramientas para desarrolladores

Se han añadido los siguientes paquetes al módulo `apps.sh`:
- python
- pip
- nodejs
- npm
- uv
- nvm (a través de una función de instalación)

Esto proporciona un entorno de desarrollo más completo desde el
principio.

* feat(apps): Añadir drivers de video adicionales para Intel

Para mejorar la compatibilidad y el rendimiento de la aceleración de video en hardware Intel Iris Xe, se han añadido los siguientes paquetes:

- `libva-intel-driver`: Driver legacy para mayor compatibilidad con aplicaciones más antiguas.
- `onevpl-intel-gpu`: Librería de la nueva generación oneVPL para el procesamiento de video moderno.

Esto asegura una cobertura de códecs más completa.
