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.
- Added speedtest-cli to the list of applications installed via pacman.
- Included a system update command to prevent dependency conflicts, with error handling for update failures.
