refactor: extract lib.rs, remove club module, add bounded concurrency

- Extract shared types (Car, BestCarRecord, AnalysisContext) into src/lib.rs
- Replace global static BEST_CARS with injected AnalysisContext for testability
- Add semaphore-bounded concurrency (limit 20) in parse_all_times()
- Replace hardcoded track name match with track_names.json loaded via include_str!
- Replace magic number 115 with const MAX_RQ: u8 = 113
- Improve floating-point tie comparison with TIME_TOLERANCE (5ms) constant
- Remove src/club.rs binary (topdrives.club no longer maintained)
- Remove scraper dependency from Cargo.toml
- Remove tracks.txt (replaced by track_names.json)
- Remove empty/placeholder test bodies
- Improve error handling in get_file() for response body read
- Add load_my_cars_data() combining owned + wishlist extraction in one I/O
- Update CHANGELOG, README, and all docs to reflect changes

-```toml

-**Purpose**: HTML parsing and CSS selector engine for web scraping
-
-**Features Used**:
-- CSS selector parsing with `Selector::parse()`
-- HTML document parsing with `Html::parse_document()`
-- Element selection and text extraction
-
-**Why Needed**:
-- Alternative data source for club.rs module
-- Parse car data from topdrives.club HTML tables
-- Extract performance information from web pages
