Pull Request Overview
This PR optimizes filesystem search performance by skipping version control system directories (.git, .hg, .svn, .jj) that typically contain many files but never produce matches. It restructures the codebase to be more modular by separating search functionality from scanning, while simplifying the concurrency model.
Key changes:
- Introduced a configurable Searcher component that can exclude VCS directories
- Replaced the worker pool pattern with a semaphore-based approach for cleaner concurrency control
- Added context support for cancellation throughout the scanning process

These can have lots of files and should never produce a match, so not bothering to iterate them can make things more efficient. This also restructures the bounded concurrency model a bit to be more simple, while extracting the initial filesystem walk code to make it more modular and configurable in the future.
