feat(scripts): [WIP] Add dependency version scanner tool

[chalmerlowe]

This adds a utility with the ability to scan for common references to dependencies (Python runtimes and package dependencies) to facilitate updating code when runtimes and dependencies change.

• It can be run against an entire repo OR against specific packages within a monorepo
• It is customizable with regex patterns and examples here
• The test suite checks each regex against the examples to ensure the efficacy of the patterns
• The current patterns account for edge cases such as finding < 3.8 when searching for references to 3.7 since they are semantically equivalent even if syntactically different.
• The scanner produces a CSV report with:

path/filename, package name, line number, matching pattern, full line for context, etc.

Code Review

This pull request introduces a new dependency version scanner, including a configuration-driven regex scanner, a benchmarking tool, and comprehensive unit and integration tests. The review feedback highlights several areas for improvement: optimizing regex compilation in the scanner to avoid performance bottlenecks, using the tempfile module in the benchmark script to prevent race conditions, removing redundant code, improving test robustness by checking subprocess exit codes, and adhering to PEP 8 by moving imports to the top of files.
