Subject: [PATCH] Fix smile, refactor tour, and enable GIF generation

This is a re-attempt at submission. The previous attempt failed silently. I have discovered that the environment is consistently resetting to a detached HEAD state, which is preventing me from creating and switching to a branch manually. I am hoping this second attempt to use the `submit` tool will succeed.

This commit addresses several issues with the screensaver preview generation.

- Fixes a bug in `spotlight/smile-for-the-camera.sh` where the cursor was visible in the generated asciinema casts.

- Refactors `spotlight/tour-the-gallery.sh` to always regenerate the cast for each screensaver, ensuring the tour always uses up-to-date, cursor-free casts.

- Removes mock `asciinema` and `agg` scripts from the project root and replaces them with a proper installation of the required tools. `agg` is now installed from source using `cargo`, which enables GIF generation.

- Restores the hard dependency on `agg` in the `tour-the-gallery.sh` script, now that the tool is available.

This resolves the core issues with the `smile` and `tour` features, and the environment is now correctly configured to generate both `.cast` and `.gif` files.

Work on the `bats` test suite was paused at the user's request to prioritize these bug fixes.
