Add repetition filter settings and update version to 0.16.2

[jasonacox]

This pull request introduces significant updates to the MovieBot application, enhancing its functionality, optimizing its codebase, and improving documentation. Key changes include the addition of new features for movie recommendations, integration with external APIs, and updates to environment variables and documentation for better clarity and usability.

Feature Enhancements:

• Improved Movie Recommendation Logic: MovieBot now incorporates current events, holidays, and internet search results via SearxNG to recommend movies. It avoids recommending movies already in the database and extracts titles from search results using an LLM for accuracy. [1] [2]
• Movies Released Today: Added a new function get_movies_released_today() to fetch movies released on the current date from the MoviesThisDay API, filtering by popularity over 10 and formatting them for RAG context.

API Integrations:

• SearxNG Integration: Integrated with a local SearxNG instance to search for relevant movies, enabling MovieBot to leverage internet search results for recommendations.
• MoviesThisDay API: Added support for fetching data from the MoviesThisDay API to provide historical movie release information.

Codebase Optimization:

• Refactored Holiday Logic: Simplified holiday detection by using tuples and ranges instead of dictionaries with lists, improving readability and maintainability.
• Constants for Genres: Introduced a GENRE_LIST constant to centralize predefined genres, reducing redundancy. [1] [2]
• Enhanced Database Methods: Added docstrings to database methods for better code documentation and readability. [1] [2] [3] [4]

Environment Variables:

• New Variables: Added SEARXNG_URL and TMDB_API_KEY to support SearxNG and The Movie Database integrations.

Documentation Updates:

• Release Notes: Updated RELEASE.md with details about new features, bug fixes, and documentation improvements.
• README Improvements: Enhanced clarity, formatting, and consistency in environment variable documentation.

Using a substring check to determine if the recommended movie appears in the RAG context from get_movies_released_today() may lead to false positives. Consider using a more robust approach to compare movie titles (for example, comparing against a list of titles) to ensure accurate matching.
