feat: Add Sentiment and UI Changes (#14)

-   Adds a `Sentiment` enum with friendly names and leading icons for `HAPPY`, `NEUTRAL`, and `SAD`.
-   Replaces the previous `Greeting` class with this new `Sentiment` based approach.
-   Updates the main UI (`App`) to use `FilterChip` for sentiment selection.
-   Adds a `TextField` for user comments and a "Submit" button.

Closes #1
