⚡ Bolt: [performance improvement] Pre-compile regex patterns in keyword density

[anchapin]

💡 What: Moved title_patterns and company_patterns regular expressions from within _extract_job_details to the module level as pre-compiled regex objects (_TITLE_PATTERNS and _COMPANY_PATTERNS).
🎯 Why: To avoid repeated regex parsing and compilation on every execution of _extract_job_details, which runs for every parsed job description. This removes unneeded overhead.
📊 Impact: Minor processing time reduction for keyword density analysis. Removing compiling from a loop/function is a standard performance best practice in Python.
🔬 Measurement: Running the test suite (python -m pytest tests/test_keyword_density.py) confirms no breakage in the keyword matching and logic extraction behavior.

Reviewer's Guide

Pre-compiles the regex patterns used to extract job title and company from job descriptions in keyword_density.py to avoid recompilation on each function call, while updating the extraction logic to use these compiled patterns.

File-Level Changes

Change	Details	Files
Pre-compile job title extraction regexes at module level and update extraction logic to use them.	Introduce a module-level _TITLE_PATTERNS list containing compiled regex objects for common job title patterns. Remove the local title_patterns list of raw regex strings within _extract_job_details. Change the title extraction loop to iterate over _TITLE_PATTERNS and call pattern.search(job_description) without passing flags each time.	cli/utils/keyword_density.py
Pre-compile company name extraction regexes at module level and update extraction logic to use them.	Introduce a module-level _COMPANY_PATTERNS list containing compiled regex objects for common company name patterns. Remove the local company_patterns list of raw regex strings within _extract_job_details. Change the company extraction loop to iterate over _COMPANY_PATTERNS and call pattern.search(job_description) without passing flags each time.	cli/utils/keyword_density.py
